Answer:

1

Explanation:

The average rate of change is measured as


(f(b)-f(a))/(b-a) in the closed interval [ a, b ]

here [ a, b ] = [ - 5, 5 ]

f(b) = f(5) = - 5² + 5 + 3 = - 25 + 8 = - 17

f(a) = f(- 5) = -(- 5)² - 5 + 3 = - 25 - 2 = - 27

Hence

average rate of change =
(-17-(-27))/(5-(-5)) =
(10)/(10) = 1
