Let f(x) = 3x^2 - 7 and g(f(4)) = 9. What is g(f(-4))?

 

So I figured out that f(4) and f(-4) both equal 41... but I'm not sure what to do in g(f(4)) = 9 since there's no variable...

Note that f(-4) = f(4) . 
 

You should be able to take it from here.

Well yes I figured that out, but I'm still not sure what to do...
