What is the definition of an inverse function?

Back

An inverse function reverses the operation of the original function, such that f(f^-1(x)) = x.

How do you find the inverse of a linear function?

Back

To find the inverse, swap x and y in the equation and solve for y.

Front

What is the graphical representation of inverse functions?

Back

Inverse functions are reflections of each other across the line y = x.
