How do you find the inverse function of #f(x)=x^3+5#?
1 Answer
Explanation:
Set
It's okay to write the answer as
Swapping the variables is a good idea when you want to graph both functions in the same picture while seeing the "reflection property" of a function and its inverse across the line
Do note that the original function is indeed a one-to-one function since its graph passes the horizontal line test (see the graph below). There's no need to restrict its domain in any way.
graph{x^3+5 [-40, 40, -20, 20]}
