Find the limit of the function (if it exists). (If an answer does not exist, enter DNE.) x² – 64 lim x--8 x + 8 Write a simpler function that agrees with the given function at all but one point. Use a graphing utility to confirm your result. g(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.

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

The graph of fx=1/x is a .
