The function y = 0.02x + 245.50, 0

The function 0.02x +245.50, o < x < 100 approximates the exhaust temperature y in degrees Fahrenheit, where x is the percent load for a diesel engine. (a) Find the inverse function. What does each variable re resent in the inverse function? x = percent load for a diesel engine; y = temperature in degrees Fahrenheit x = temperature in degrees Fahrenheit; y = percent load for a diesel engine (b) Use a graphing utility to graph the inverse function. 100 80 60 20 100 100 80 60 20 100 200 200 300 300 400 400 500 500 100 80 60 20 100 100 80 60 20 100 200 200 300 300 400 400 500 500 (c) The exhaust temperature of the engine must not exceed 500 degrees Fahrenheit. What is the ercent load interval? (Round our answers to two decimal places.)
