Front

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What does it mean for a function to be vertically stretched by a factor of 8?

Back

A vertical stretch by a factor of 8 means that every y-value of the function is multiplied by 8, making the graph taller.

Front

What is the parent absolute value function?

Back

Front

How do you find the inverse of a function?

Back

To find the inverse of a function, swap the x and y variables and solve for y.

Front

What does reflecting a graph over the line y = x mean?

Back

Reflecting a graph over the line y = x means that for every point (a, b) on the graph, the point (b, a) will also be on the graph.

What is an absolute value equation?

Back

Front

What is the effect of a negative sign in front of an absolute value function?

Back

A negative sign in front of an absolute value function reflects the graph over the x-axis.

Front

What does it mean for a function to be one-to-one?

Back

A function is one-to-one if it passes the horizontal line test, meaning no horizontal line intersects the graph more than once.
