Average rate of change = 5

Step-by-step explanation:

Average rate of change of a function is defined by the expression over the interval a ≤ x ≤ b,

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

Using this rule for the average rate of change of the function (defined by the table) over the interval 4 ≤ x ≤ 5,

Average rate of change = \frac{f(5)-f(4)}{5-4}

From the table,

f(5) = 10

f(4) = 5

Therefore, average rate of change of the function = \frac{10-5}{5-4}

                                                                                    = 5
