I think A, but im not 100% sure
Option b. 0.496
- Step-by-step explanation:
we know that
f(x)=0.01(2^{x})
The average rate of change is equal to
\frac{f(b)-f(a)}{b-a}
where
a=3
b=8
f(a)=f(3)=0.01(2^{3})=0.08
f(b)=f(8)=0.01(2^{8})=2.56
Substitute
\frac{2.56-0.08}{8-3}
\frac{2.48}{5}
0.496
First, make it an improper fraction, 7x4 is 28. 28+1 is 29. So the improper fraction is 29/7. Then, divide 29 by 7. The answer is 4.14 rounded to the tenths place.
