Answer:

Average rate of change; 1

Explanation:

g(x) = x^(2) + 10x + 20

$-9\leq x\leq 0$

1. Find the end-points of the given interval

Input (-9) and (0) into the equation.

Input (-9)

(-9)^2 + 10(-9) + 20

81 - 90 + 20

11

point is; (-9, 11)

Input (0)

(0)^2 + 10(0) + 20

0 + 0 + 20

20

point is; (0, 20)

2. Find the slope

Now find the slope between the two points, the equation for the slope is;

(y_(2)-y_(1))/(x_2-x_1)

Substitute in the points;

(11-20)/(0-(-9))

-
(9)/(9)

= -1
