Question

The Inverse of F(x) is a function. True or False.

Answer 1

True.
For example: if we have the function y=4x+2, then the inverse will be x=(y-2)/4.

Answer 2

thank you! i appreciate this example as well!

Answer 3

False.

Consider the function y = x^2.

If it had an inverse, it would look like x = y*2 with y = +/- sqrt(x)

If x were 4, y would equal 2 or -2 which violates the rule for a function.
