I'm having trouble with an inverse function problem in Cal 2:
Find the value of the derivative of the inverse of the function.
Given that f(x)=4^(sqrt(x))x+3, find f1'(3).
I can't figure out what to do with the constant raised to the power of sqrt(x)

Best ResponseYou've already chosen the best response.0The easiest way to find an inverse of a function is to simply swap the x and the y (or in this case "f(x)") and then solve for f(x). Is it this: \[4^{\sqrt{x}}x3=f(x)?\] or this: \[4^{\sqrt{x}x3}=f(x)?\]
