cwrw238 · Answer

exponential growth would be something like y = 2x^a  where a is a number greater than 1

aum · Answer

In $\large y = a(b)^x$, if $\Large b \gt 1$, then it is an exponential growth.

If $\Large b \lt 1$, then it is an exponential decay.

I got C, Am I right?

anonymous · Answer

no, the correct answer is A. 
when is an exponential growth, means is increasing, the rate of change would be grater than 1. when is decreasing the rate of change will be a decimal
