Answer:

The average rate of change of the function
f(x) from
x=0 to
x=2 is equal to 6.

Explanation:

Let's define the average rate of change of the function
f(x) over the interval [a,b] :


A(x)= Δf / Δx =
(f(b)-f(a))/(b-a)

In the exercise,
a=0 and
b=2

Now we calculate
f(a) and
f(b)


f(a)=f(0)=4.(2^(0))=4.1=4


f(b)=f(2)=4.(2^(2))=(4).(4)=16


f(b)-f(a)=16-4=12 and
b-a=2-0=2

Finally, the average rate of change is


(f(b)-f(a))/(b-a)=(12)/(2)=6
