need help.

The relationship between an input and the voltage of a device is: V=A cos f(x) where A=20. Find the function that expresses the signal input for a given voltage value

The original question says find f^-1 for the function f. f(x)=4x^2-2,x≥0 I found f^-1(x)= to be y=4x^2-2 and then did inverse function and found the fraction answer above I just don't...

Just not sure how to solve or what the question is asking for the exam help would be much appreciated thanks!
