Front

What does the horizontal line test determine about a function?

Back

It determines if the function has an inverse function.

Front

Does the function pass the horizontal line test if it has an inverse?

Back

Yes, if it passes the horizontal line test, it has an inverse.

Back

(-1, -2), (-3, -8), (3, -6).

Front

What is a vertical stretch in a function?

Back

A vertical stretch occurs when the output values of a function are multiplied by a factor greater than 1.

Front

What is a horizontal shift in a function?

Back

A horizontal shift moves the graph of a function left or right along the x-axis.

Front

What is a vertical shift in a function?

Back
