(a) Show that f(x)=6x-2 defines a one-to-one function. A function is one-to-one if it can be shown that if f(a) = f(b), then = =. Assume f(a) = f(b). Part: 1/4 x

How do you find the domain for the composition of two functions, fg ?

An outpatient operating room charges each patient a fixed amount per surgery plus an amount per minute for use. One patient was charged 250 for a 30-minute surgery and another patient was charged 450 for a 90-minute surgery. Determine the linear function that would be used to compute the charges. Use the function to determine the charge when a patient has a 45-minute surgery.
