Question

Using complete sentences, explain the limitations on the base of an exponential function

Answer 1

The base? Hmmm.
Well it can never be 0.

Think about a^x
if x=0

Then a^0 = 1
Hmmm there is no power that will give us a^x=0 (except in the limit).

What else can we say, hmmmmm :o

Answer 2

That's good! Thank you!
