Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.
y=64(0.13)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1
