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.

Briana drew a rectangle with a width 5 inches shorter than its length. She measured the perimeter of the rectangle and found it

Zigmanuir [339]

P = 2(L + W)
P = 14
W = L - 5

14 = 2(L + L - 5)
14 = 2(2L - 5)
14 = 4L - 10
14 + 10 = 4L
24 = 4L
24/4 = L
6 = L.......the length is 6 inches

W = L - 5
W = 6 - 5
W = 1 <=== the width is 1 inch
