Chapter 1, Problem 1.376(choose chapter or problem)
The Baylor GPA Scale Revisited (See in Section 1.2.) The function used to convert Baylor School percentage grades to GPAs on a 4-point scale is
\(y=\left(\frac{3^{1.7}}{30}(x-65)\right)^{\frac{1}{1.7}}+1\)
The function has domain [65, 100]. Anything below 65 is a failure and automatically converts to a GPA of 0.
(a) Find the inverse function algebraically. What can the inverse function be used for?
(b) Does the inverse function have any domain restrictions?
(c) Verify with a graphing calculator that the function found in (a) and the given function are really inverses.
