Answer
a. $g(2) = 25$
b. $(25,2)$
c. $f(25) = 2$
Work Step by Step
a. The x value of the ordered pair is the input to the function and the y value is the output
b. An ordered pair where the x and y values of function $f$ are switched is a solution to $f^{-1}$
c. The x value of the ordered pair is the input to the function and the y value is the output
