Answer 1

Answer:

Average rate of change = 10

Explanation:

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

a = 2

f(a) = f(2) = (-2)² + 3(2) + 1 = 4 + 6 + 1

f(a) = 11

b = 5

f(b) = f(5) = (-5)² + 3(5) + 1 = 25 + 15 + 1

f(b) = 41

Thus:

Average rate of change = $\frac{41 - 11}{5 - 2}$

$= \frac{30}{3} = 10$

Average rate of change = 10
