Question 48861
Yes, exponential decay and exponential growth exists.
Exponential Decay
{{{f(x) = a(b^x)}}} where {{{0 < b < 1}}}
ex.) {{{f(x) = 2(1/2)^x}}}
{{{graph(600,600,-10,10,-10,10,2(1/2)^x)}}}
Exponential Growth
{{{f(x) = a(b^x)}}} where {{{b > 1}}}
ex.) {{{f(x) = 2(2)^x}}}
{{{graph(600,600,-10,10,-10,10,2(2)^x)}}}
