How do the average rates of change for the functions f(x) = 2x2 and g(x) = 3x2 over the interval −3 ≤ x ≤ 4 compare?
DedPeter [7]
<h2>Answer with explanation:</h2>

The average rate of change for function f(x) over the interval a ≤ x ≤ b is given by :-

\dfrac{f(b)-f(a)}{b-a}

So, the rate of change for function f(x)=2x^2  over the interval −3 ≤ x ≤ 4 :

=\dfrac{2(4)^2-2(-3)^2}{4-(-3)}=\dfrac{14}{7}=2

The rate of change for function g(x)=3x^2  over the interval −3 ≤ x ≤ 4 :

=\dfrac{3(4)^2-3(-3)^2}{4-(-3)}=\dfrac{21}{7}=3

So, the rate of change for  g(x) is greater than f(x) over the interval −3 ≤ x ≤ 4.
