Which functions are invertible?

Select each correct answer.

Let's see if I remember this....

 

A function has to pass the "horizontal line" test to be a strict inverse....that is......any horizontal line drawn can only cut the function one time....

 

So...the two functions on the left will be strictly invertible, but not those on the right
