1 . A company produces cases for smartphones. The cost, in dollars, for producing x cases is approximated by C = f (x) =98, 100+7.2x . (A) What are the input and output variables and their meanings for the inverse function? Inverse Inverse Variables Inverse Meanings Input Output (B) Determine a formula for the inverse function, using proper inverse function notation. (C) Use the inverse function to determine the number of cases that could be produced for a cost of $360,000. Round your answer to the nearest whole number of cases and include units with your
