Identify whether the set of ordered pairs represent an exponential function. Explain your answer.(-1,4.) ( 0,8) (1,16) (2, 32)A.not an exponential functionAs the x-values are increased by a constant amount, the y-values increase by the same amount.B.not an exponential functionAs the x-values are increased by a constant amount, the y-values are not multiplied by a constant amount.C.exponential functionAs the x-values are increased by a constant amount, the y-values are multiplied by a constant amount.D.exponential functionAs the x-values are increased by a constant amount, the y-values increase by the same amount.
