# Thread: Find the inverse. Is it a function

1. ## Find the inverse. Is it a function

I understand how to find the inverse but I am just stumped to why it isnt a function

f(x)=6x^2 - 12

Are you asking why $f(x)=6x^2 - 12$ has no inverse?
If not what are you asking?

It is a function, but not one to one. You can restrict the domain to make it one to one, then you can find the inverse.
