1.5.2 Exponentials and logarithms

What feature makes y=axy=a^xy=ax an exponential function?

A

The variable xxx appears in the exponent.

B

The variable is the base, not the exponent.

C

As x→−∞x\to-\inftyx→−∞, ex→0\boxed{e^x\to0}ex→0​, so the horizontal asymptote is y=0y=0y=0.

D

Reflection in the xxx-axis.
