Graphs And Functions Vocabulary

The Distance Formula is a mathematical formula used to determine the distance between two points in a coordinate plane by calculating the length of the line segment connecting the two points.

The Midpoint Formula is specifically used to find the point that is exactly halfway between two given points on a line segment, while the other options are not related to this concept.

A circle is defined as a shape consisting of all points in a plane that are a fixed distance from a given point called the center. It does not involve straight sides or angles like the incorrect answers provided.

A linear equation is a first-degree equation where the highest power of the variables involved is 1. The graph of a linear equation is always a straight line.

The X-Intercept is the point where the graph crosses the x-axis. It is important in understanding the behavior of a function or equation in relation to the x-axis.

The Y-intercept is specifically related to the y-axis, not the x-axis, the maximum point, or intersections with other lines.

Finding the zero of an equation means determining the value(s) for the variable that make the equation true, essentially solving the equation.

The term 'root of an equation' refers to the values that make the equation true, or in other words, the solutions to the equation.

Slope refers to the measure of how steep a line is, usually represented as the ratio of the vertical change between two points to the horizontal change between the same points.

The Point-Slope Form of an Equation is y - y1 = m(x - x1) where m is the slope of the line and (x1,y1) is a point on the line. This form is useful for finding the equation of a line given its slope and a point on the line.

The correct Slope-Intercept Form of an Equation is y = mx + b where m represents the slope of the line and b is the y-intercept. The incorrect answers provided have variations in the placement of variables or incorrect interpretations of the slope-intercept form.

Perpendicular lines are defined as two lines that intersect at a right angle, with slopes that are opposite reciprocals of each other. This relationship is distinct from lines that never intersect, parallel lines, or lines that intersect at acute angles.

Parallel lines are two lines in a plane that do not intersect at any point. They are always the same distance apart and will never converge.

A function is defined as a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. It represents a specific kind of relation or mapping between a set of inputs and a set of permissible outputs.

The Vertical Line Test is a method to determine if a graph represents a function by checking for the uniqueness of y-values when intersected by vertical lines. If a vertical line intersects the graph at more than one point, then the graph does not represent a function.

The domain of a relation consists of all the input values, which are the first coordinates of the ordered pairs in the relation. It helps determine the independent variable values that the relation is defined for.

In mathematics, the range of a relation refers to the set of all second coordinates of the ordered pairs in that relation. It helps in determining the output values of the relation.

A parabola is a U-shaped curve that represents the graph of a quadratic function. It is not a circle, straight line, or exponential curve.

An even function is defined by the property f(-x) = f(x), meaning it is symmetric about the y-axis. This distinguishes it from the other incorrect options provided.

A one-to-one function ensures that each input (x-coordinate) maps to a unique output (y-coordinate), thereby representing a true function relationship without duplicates.

An inverse function is obtained by exchanging the x and y coordinates in each ordered pair of the original function, allowing the function to 'reverse' the original function's process.
