Question

A logarithmic function, h, is plotted on the graph. What is the approximate rate of change of this function on the interval [-2,2]?​

Answer 1

Answer:

C: - 9/8

Step-by-step explanation:

interval:  -2 ≤ x ≤ 2

Find 2 coordinate points on the graph where x = -2 and x = 2:

(-2, 2)  and (2, -2.5)

Let $(x_1,y_1)$ = (-2, 2)  and  $(x_2,y_2)$ = (2, -2.5)

rate of change = $\frac{y_2-y_1}{x_2-x_1}=\frac{-2.5-2}{2+2} =\frac{-4.5}{4}=-\frac{9}{8}$

Answer 2

C. -$\frac{9}{8}$
