Inverse functions essentially “reverse” what the original function did. You likely encountered Inverse Functions in Algebra II and/or Pre-Calculus when reflecting a function along y = x.
We denote functions as f(x) and their inverses as f^-1(x).
Calculating the derivative of an Inverse function isn’t really much more difficult than deriving normal functions - it simply requires knowing the formula:
Let’s look at an example problem to clarify!
