Answer:
Step-by-step explanation:
The inverse function for a set of ordered pairs can be found by swapping the x- and y-coordinates in each pair.

__
The inverse of a function expressed algebraically can be found by swapping the x- and y-variables and solving for y.

A function of its own inverse returns the original value:

Answer:
So,
if C = 2πR
you take 2π you get 6.28
so C=6.28 x r
the radius is 11.5 so
6.28 x 11.5 = 72.2566
the circumference is 72.2566
Step-by-step explanation:
Yes, the common factor is (2x+5) and the equation can be expressed as:
(x^3-4)(2x+5)
