Question
The function
y = 0.02x2 + 245.50, 0 < 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.
y =
What does each variable represent 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
