The function y = f(x) is graphed below. What is the average rate of change of the function f(x) on the interval – 7 < x < -3?

it's

you have to put the graph on here with the question

step-by-step explanation:

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
