Answer:

Step-by-step explanation:
A way to find the inverse function is to swap the x and y (f(x)) in the equation.

We can check that it is an inverse function by using a property of inverse functions:

If we plug in the f(x) function into the variable x of the inverse function, we should end up with x

It checks out!
Answer:

Step-by-step explanation:
a²+b²=c² so: 33²+15²=x²
1089+225=x²
1314=x²
take the square root of both sides
36.249=x or

=x
