Question

Determine whether the rule represents an exponential function. Explain why or why not.
y=-10 times x^2

A.
Since the independent variable x the​ exponent,y=-10 times x^2 represents an exponential function.
B.
Since the independent variable x the​ exponent,y=-10 times x^2 does not represent an exponential function.
C.
Since the independent variable x is not the​ base, y=-10 times x^2 does not represent an exponential function.
D.
Since the independent variable x is the​ base,y=-10 times x^2 does represent an exponential function.
