What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

What is the vertical line test?

Back

The vertical line test is a method to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, it is not a function.

What does it mean for a relation to be a function?

Back

A relation is a function if each input (x-value) has exactly one output (y-value). No x-value can correspond to more than one y-value.

What is a function mapping?

Back

A function mapping shows how each element of a set (domain) is paired with an element of another set (range).

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function may have multiple outputs for a single input.
