Determine if the equation y = 2(0.4)x represents exponential growth or decay.

In this format, we can either use latex or enter a "^" to show that we are raising something to a power

y=2(0.4)^x

This is exponential decay because the rate is less than 1, in this case 0.4.

All exponential functions can be expressed as:

F=Ir^t, F=final amount, I=initial amount, r=rate, t=time

There should only be 1 solution
