Step-by-step explanation:

The average rate of change is measured as

$\frac{f(b)-f(a)}{b-a}$ in the closed interval [ a, b ]

here [a, b ] = [ - 3, 8 ]

f(b) = f(8) = 8² + 3(8) - 4 = 64 + 24 - 4 = 84

f(a) = f(- 3) = (- 3)² + 3(- 3) - 4 = 9 - 9 - 4 = - 4

average rate of change = $\frac{84-(-4)}{8-(-3)}$ = $\frac{88}{11}$ = 8
