You have to calculate the rise over run. See how many times it rises from the bottom. Then see how many times it takes horizontally to get to the next corner. Not sure if this helped but I tried sorry lol (but dw the answer is correct)
it goes like this f(t)=P(1+r)^t r=rate of decay or grouth if r>0 then it is grouth by r if r<0 then it is decay i P=initial amount so given f(x)=5500(1.65)^t f(x)=5500(1+0.65)^t 0.65>0 so it is growing by 65%
