Best ResponseYou've already chosen the best response.0I did the horizontal line test to the original function, which was instructed, and found that it was not a function, but after doing it algebraically, it is a function. Can someone tell me what I did wrong?

Best ResponseYou've already chosen the best response.0The inverse of f(x)=x^24 is + \[\sqrt{x+4}\] If you graph both of those, one of them is a function while the inverse is a function.
