About This Quiz

When it comes to calculus, a limit is described as a number that a function approaches as the independent variable of the function approaches a given value. On the other hand, a continuity is reflected on a graph illustrating a function,where one can verify whether the graph of a function can be traced without lifting his/her pen from the paper. Try our quiz to test your knowledge about limits and continuity.

    In the function f(x)=3x, what is the limit of f(x) as x approaches 2? - ProProfs

    In the function f(x)=3x, what is the limit of f(x) as x approaches 2?

    • 3

    • 6/2

    • 6

    • 6/3

    Correct Answer
    A. 6
    Explanation
    The given function is f(x) = 3x. To find the limit of f(x) as x approaches 2, we substitute 2 into the function: f(2) = 3(2) = 6. Therefore, the limit of f(x) as x approaches 2 is 6.

    What is the core function of continuity? - ProProfs

    What is the core function of continuity?

    • Topology

    • Mechanics

    • Architecture

    • Geography

    Correct Answer
    A. Topology
    Explanation
    Topology is the branch of mathematics that deals with the properties of space that are preserved under continuous transformations. It studies the concepts of continuity, connectedness, and compactness. Therefore, the core function of continuity is related to topology, as it is a fundamental concept in this field of study.

    What is the symbol used for limit with calculus? - ProProfs

    What is the symbol used for limit with calculus?

    • Lim x

    • Lim of x

    • Limā†’x

    • Xā†’āˆž

    Correct Answer
    A. Limā†’x
    Explanation
    The symbol used for limit with calculus is "limā†’x". This notation represents the concept of taking the limit of a function as the variable "x" approaches a certain value. In this case, the limit is being taken as "x" approaches a specific value, which is represented by the arrow above the "lim" symbol.

    What is a Hausdorff space? - ProProfs

    What is a Hausdorff space?

    • It's T1

    • It's T2

    • It's a topological space in which distinct points have disjoint neighborhoods.

    • It's a topological base in which distinct points have disjoint neighborhoods.

    Correct Answer
    A. It's a topological space in which distinct points have disjoint neighborhoods.
    Explanation
    A Hausdorff space is a topological space in which distinct points have disjoint neighborhoods. This means that for any two distinct points in the space, there exist open sets containing each point respectively, such that the intersection of these open sets is empty. This property ensures that points in a Hausdorff space can be separated from each other, making it a stronger condition than just being T1 or T2.

    What does R represent? - ProProfs

    What does R represent?

    • The real line

    • The continuity

    • Infinity

    • A curve

    Correct Answer
    A. The real line
    Explanation
    R represents the real line, which is a straight line that extends infinitely in both directions. It includes all the real numbers, both positive and negative, and is used to represent the set of all possible values that a variable can take. The real line is a fundamental concept in mathematics and is often used in calculus, geometry, and other branches of mathematics to represent and analyze quantities and relationships.

    Who is considered to be the godfather of the modern idea of the limit of a function? - ProProfs

    Who is considered to be the godfather of the modern idea of the limit of a function?

    • Spinoza

    • Bolzano

    • Boltzmann

    • Newton

    Correct Answer
    A. Bolzano
    Explanation
    Bolzano is considered to be the godfather of the modern idea of the limit of a function. He made significant contributions to the development of calculus and the concept of limits. Bolzano's work laid the foundation for the rigorous definition and understanding of limits, which is a fundamental concept in modern mathematics and analysis. His ideas and insights were influential in shaping the way we understand and study functions and their behavior.

    What is a topological space? - ProProfs

    What is a topological space?

    • It's a set of values with a set of neighborhood for each point.

    • It's a set of neighborhood for each point.

    • It's a set of points with a set of neighborhood for each point.

    • It's a set of functions with a set of neighborhood for each point.

    Correct Answer
    A. It's a set of points with a set of neighborhood for each point.
    Explanation
    A topological space is a mathematical concept that consists of a set of points along with a collection of neighborhoods for each point. This means that for every point in the set, there is a corresponding set of other points that are considered "nearby" or within the neighborhood of that point. This definition captures the essence of a topological space, where the relationships between points and their neighborhoods are fundamental to understanding the properties and structure of the space.

    In what Century did the concept of continuity appear? - ProProfs

    In what Century did the concept of continuity appear?

    • 17th Century

    • 19th Century

    • 20th Century

    • 18th Century

    Correct Answer
    A. 19th Century
    Explanation
    The concept of continuity appeared in the 19th Century. This was a time when mathematicians and scientists began to study and develop the idea of continuous functions and the properties they possess. Prior to this, the concept of continuity was not well understood or explored. The 19th Century marked a significant advancement in the understanding and application of continuity in various fields of study, including mathematics, physics, and engineering.

    How can you describe a neighborhood in topology? - ProProfs

    How can you describe a neighborhood in topology?

    • It's a graph that contains all points of the domain within some fixed distance of c.

    • It's a set that contains all points of the domain within some fixed distance of c.

    • It's an area that contains all points of the domain within some fixed distance of c.

    • It's a shape that contains all points of the domain within some fixed distance of c.

    Correct Answer
    A. It's a set that contains all points of the domain within some fixed distance of c.
    Explanation
    A neighborhood in topology is described as a set that contains all points of the domain within some fixed distance of c. This means that any point within a certain distance from a given point c is considered part of the neighborhood. It does not necessarily have to be an area or a shape, but rather a set of points that satisfy the distance constraint.
