    How to identify discontinuous piecewise functions? - ProProfs

    How to identify discontinuous piecewise functions?

    • Breaks, holes, jumps

    • Smooth transition

    • Highlighted in purple

    • Disjointed lines is used for representation

    Correct Answer
    A. Breaks, holes, jumps
    Explanation
    Discontinuous piecewise functions can be identified by looking for breaks, holes, and jumps in the graph. These are points where the function is not continuous and there is a discontinuity in the graph. Smooth transitions are not present in these functions, and instead, there are disjointed lines used for representation. Therefore, breaks, holes, and jumps are the key indicators for identifying discontinuous piecewise functions.

    How many equations (at the least) define a piecewise function? - ProProfs

    How many equations (at the least) define a piecewise function?

    • 3

    • 2

    • 1

    • 4

    Correct Answer
    A. 2
    Explanation
    A piecewise function is defined by different equations in different intervals or regions. At the least, a piecewise function requires two equations to define it. One equation will define the function in one interval and another equation will define it in a different interval. Therefore, the correct answer is 2.

    What's another name of step function? - ProProfs

    What's another name of step function?

    • Irregular block function

    • Staircase function

    • Symmetrical step function

    • Coordinated function

    Correct Answer
    A. Staircase function
    Explanation
    The step function is often referred to as the "staircase function" because its graph resembles a series of connected stair steps. It is called so because the function jumps from one constant value to another at specific intervals, creating a step-like pattern. The term "staircase" accurately describes this behavior and is commonly used to describe the step function.

    Which one do you think is a fact in piecewise defined functions? - ProProfs

    Which one do you think is a fact in piecewise defined functions?

    • Continuous

    • Discontinuous

    • Continuous and discontinuous

    • Linear

    Correct Answer
    A. Continuous and discontinuous
    Explanation
    A piecewise defined function can have both continuous and discontinuous parts. This means that certain intervals of the function may exhibit continuity, while other intervals may have points of discontinuity. Therefore, the statement "Continuous and discontinuous" is a fact in piecewise defined functions.

    What happens if the graph opens downwards? - ProProfs

    What happens if the graph opens downwards?

    • Range will always be equal to the vertex

    • Range will be infinite

    • Range will be greater than the vertex

    • Range will be less than or equal to y-coordinate of the vertex

    Correct Answer
    A. Range will be less than or equal to y-coordinate of the vertex
    Explanation
    When the graph opens downwards, it means that the vertex of the parabola is at its highest point. In this case, the range of the function will be less than or equal to the y-coordinate of the vertex. This is because the y-coordinate of the vertex represents the maximum value that the function can attain, and since the graph is opening downwards, all the y-values of the graph will be less than or equal to the y-coordinate of the vertex. Therefore, the range will be limited to values that are less than or equal to the y-coordinate of the vertex.

    What's the other name of piecewise functions? - ProProfs

    What's the other name of piecewise functions?

    • Split functions

    • Split-definition functions

    • Divided functions

    • It has no other name

    Correct Answer
    A. Split-definition functions
    Explanation
    Piecewise functions are also commonly referred to as split-definition functions. This is because these functions are defined by different equations or expressions over different intervals or "pieces" of the function's domain. Each piece of the function has its own separate definition, hence the term "split-definition functions". The other options listed in the question, such as "split functions" and "divided functions", are not commonly used terms to describe piecewise functions.

    What do you when finding the range of an absolute value function? - ProProfs

    What do you when finding the range of an absolute value function?

    • There's no vertex to begin with

    • Lowest point on X-axis

    • Vertex

    • Mid-point on Y-axis

    Correct Answer
    A. Vertex
    Explanation
    When finding the range of an absolute value function, you look for the vertex. The vertex represents the lowest or highest point on the graph, depending on whether the absolute value function is concave up or concave down. In this case, the correct answer is "Vertex" because it correctly identifies that the vertex is important when determining the range of an absolute value function.

    Do piecewise functions have parent function? - ProProfs

    Do piecewise functions have parent function?

    • Two

    • One

    • None

    • 3

    Correct Answer
    A. None
    Explanation
    Piecewise functions do not have a specific parent function. A parent function is a basic function that can be modified through transformations to create different functions. However, piecewise functions are defined differently than regular functions and involve different rules and conditions for different intervals or pieces of the function. Therefore, they do not have a single parent function that can be modified.

    What are the limitations of a piecewise function in terms of form? - ProProfs

    What are the limitations of a piecewise function in terms of form?

    • Exponential only

    • Linear only

    • Can be a combination of forms (cubic for example)

    • Option B and C

    Correct Answer
    A. Exponential only
    Explanation
    A piecewise function is a function that is defined by different expressions or formulas for different intervals or "pieces" of its domain. The limitations of a piecewise function in terms of form refer to the types of functions that can be used to define each piece of the function. The correct answer, "Exponential only," means that the pieces of the function can only be defined using exponential functions. This means that linear functions or other forms, such as cubic functions, cannot be used to define the pieces of the function.
