Best ResponseYou've already chosen the best response.2f(x) is same as y so \[\huge\rm y=0.01(2)^x\] we need y value to find average rate of change (slope) so first substitute x for 3 and then for 8 to find y value

Best ResponseYou've already chosen the best response.2let's find y when x =3 substitute x for 3 \[y=0.01(2)^3\] solve

Best ResponseYou've already chosen the best response.0Y=.08 and slope is 0?

Best ResponseYou've already chosen the best response.2y =0.08 when x= 3 right but how did you get 0 slope ?

Best ResponseYou've already chosen the best response.2well... i have to go find y when x=8 just like we did for x=3 then use slope formula \[\huge\rm \frac{ y_2 y_1 }{ x_2 x_1 }\] plugin x's and y's value
