Front

What is a function?

Back

A function is a relation between a set of inputs and a set of permissible outputs, where each input is related to exactly one output.

Front

What is the y-intercept of a function?

Back

The y-intercept is the point where the graph of a function crosses the y-axis, represented as (0, f(0)).

Front

What is an x-intercept?

Back

An x-intercept is the point where the graph of a function crosses the x-axis, represented as (x, 0).

Front

What does it mean for a function to have a root?

Back

A root of a function is a value of x for which f(x) = 0, meaning it is an x-intercept.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input is associated with exactly one output.

Front

What is the general form of a cubic function?

Back

Front

What is the significance of the leading coefficient in a polynomial function?

Back

The leading coefficient determines the end behavior of the graph of the polynomial function.

Front

How can you determine the number of x-intercepts of a polynomial function?

Back

The number of x-intercepts can be determined by finding the roots of the polynomial equation.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the graph of a parabola, depending on its orientation.
