The table shows values that represent a quadratic function
Mamont248 [21]

Answer:

- 8

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ 3, 5 ]

From the table

f(b) = f(5) = - 26

f(a) = f(3) = - 10

Hence

average rate of change = \frac{-26-(-10)}{5-3} = \frac{-16}{2} = - 8
