PLEASE HELP :3

What is the average rate of change of the function


f(x)=4(2)x from x = 0 to x = 2?

Answer 1

Please, Abby, use " ^ " to denote exponentiation: f(x) = 4(2)^x.

The rate of change of this function, on [0,2], is

4(2)^2 - 4(2^0) 16 - 4

------------------------ = --------- = 6 units per unit change in x

2 - 0 2
