1. ## Need 10th grade math help! Exponential growth/decay.

For exponential growth functions:
a>0 and b>1
Is: -(1/3)*(3^x)
still exponential growth? even though a<0
the function is noted as a(b^x)

Also, same for decay
a>0 and 0>b>1
if a is -1 would it still be an exponential decay?
decay still is a(b^x)
Example: -3(2/3)^x

Would they still be 1) exponential growth and 2) exponential decay?

I'm a little bit confused with the wording on the question...

The first equation is exponential decay, the second is exponential growth. Is that what your asking?

So 1. No, it would not still be exponential growth and 2. No, it would not still be exponential decay.

I was saying, that since a would be "-1" would the equations still be exponential decay/growth, or what would they classify as?
