Question

State whether the equation represents exponential growth, exponential decay, or neither. y=2*0.68^x

Please help!!

Answer 1

an exponential equation will look like

y = a(b)ˣ

now, the tale-tell guy is the "b" component, or growth/decay factor.

if "b" is less than 1, is decay, if "b" is greater than 1, is growth.

in this case b = 0.68, that's less than 1, so decay.

Answer 2

y=2*0.68^x = exponential decay
