The question is: If f(x)=2x-3, then find the value of f^-1(0) The part that stumps me is putting f to the power of -1. We understand how to solve the problem if it's not but to a power. Thank you so much for your help! I appreciate it greatly. -IsaacAnswer by Fombitz(13828)   (Show Source): You can put this solution on YOUR website!Isaac, it's not a power but it stands for the inverse function. For example, if I have a function such that then the inverse function, would be such that when I plug in x=5, I would get back y=1. . . . 1.To find the inverse, first change to x,y notation. Then interchange the positions of x and y and solve for y. } The solution for the new y is the inverse function. . . . Let's try it. Now when I plug in x=-1 into the inverse function, I should get back y=1. . . . You interested at the value of the inverse function for x=0. You could have also solved it by asking what x makes my original function equal to zero. The inverse functions interchange x and y values. Hopefully that makes sense. Good luck!
