Presumably, h(x)=3(5)^x. In that case,

(A)
The average rate of change over the interval 0\le x\le1 is

\dfrac{h(1)-h(0)}{1-0}=\dfrac{15-3}1=12

and over 2\le x\le3, it's

\dfrac{h(3)-h(2)}{3-2}=\dfrac{375-75}1=300

(B)
\dfrac{300}{12}=25, i.e. the average rate of change over the second interval is 25 times higher. That's to be expected; 3(5)^x is an exponential function. As x gets larger, the rate of change of h(x) gets larger too.
