Determine whether the rule represents an exponential function. Explain why or why not.
Y=-2•x^7 WILL MARK BRAINLIEST

A. Since the independent variable X is not the exponent, y=-2•x^7 does not represent an exponential function.

B. Since the independent variable X is not the base, y=-2•x^7 does not represent an exponential function.

C. Since the independent variable x is the base, y=-2•x^7 does represent an exponential function.

D. Since the independent variable X is the exponent, y=-2•x^7 represents an exponential function.
