The function
y = 0.03x2 + 245.50, 0 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 represent in the inverse function?
(b) Use a graphing utility to graph the inverse function.
(c) The exhaust temperature of the engine must not exceed 500 degrees Fahrenheit. What is the percent load interval?
