Question

Given the function defined in the table below, find the average rate of change, in simplest form, or the function over the interval 20

Answer 1

Answer:

Average rate of change = 0.4

Step-by-step explanation:

Average rate of change of a function in the interval [a, b] is defined by the formula,

Rate of change = $\frac{f(b)-f(a)}{b-a}$

From the table attached,

Rate of change of the function in the interval 20 ≤ x ≤ 40 will be

= $\frac{f(40)-f(20)}{40-20}$

= $\frac{24-16}{40-20}$

= $\frac{8}{20}$

= $\frac{2}{5}$

= 0.4

Therefore, average rate change of the function in the given interval 20 ≤ x ≤ 40 is = 0.4
