Question

Decide if the function is an exponential growth function or exponential decay function, and describe its end behavior using limits. y=0.8^x

Answer 1

Answer:

Step-by-step explanation:

This is exponential decay because the growth factor is a fraction, 8/10.  For a function to be growth, the growth factor has to be greater than 1.

As far as end behavior goes, as x approaches negative infinity, y approaches positive infinity.  As x approaches positive infinity, y approaches 0.

Is that what you meant by describing end behavior with limits?
