Determine whether the rule represents an exponential function. Explain why or why not.

Question

y=-8/x^3
Choose the correct answer below.
A.
Since the independent variable x is not the​ base, does not represent an exponential function.
B.
Since the independent variable x the​ exponent, an exponential function.
C.
Since the independent variable x the​ exponent, an exponential function.
D.
Since the independent variable x is the​ base, does represent an exponential function.

Answer 1

A. Since the independent variable x is not the base, y=-8/x^3 does not represent an exponential function.
