we have the given equation as y=f(x)=250(1.04)x we have to identify whether it is an exponential growth rate or decay rate we also have to calculate its percentage we have the function as y=f(x)=250(1.04)x it can also be written as y=f(x)=250(1+0.04)x... eq(i) the standard equation for exponential growth/decay rate is y=f(t)=x0(1+r)t where, f(t) is the value at time t x0 is the initial value at time ​​​​​​​t=0 r is the growth rate when r&amp;gt;0 or decay rate when r&amp;lt;0, in percent t is the time in discrete intervals and selected time units compare eq(i) with the standard equation x0=250 r=0.04=4% t=x as we can see r&amp;gt;0, so this is an exponential decay rate rate of decay, r=0.04 r=0.04×100 r=4%

The equation y = 250 \times 1.04^x models o exponential
