Use translations to graph the given function. 9) a(x) = /x - 2 - 1

Use the Vertical Line Test to determine whether the graph represents y as a function of x.

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.
