PLEASE HELP!!

A piecewise function f (x) is defined by f of x is equal to the piecewise function of 3 to the power of the quantity x minus 1 end quantity minus 4 for x is less than or equal to 3 and the quantity 15 over x for x is greater than 3

Part A: Based on the graph of f (x), what is the range? (5 points)

Part B: Determine the asymptotes of f (x). (5 points)

Part C: Describe the end behavior of f (x). (5 points)
