Answer:

The correct option is A.

Step-by-step explanation:

From the given table it is noticed that the function passing through the points (8,0), (5,4) and (-5,19).

The average rate of change from x₁ and x₂ is

[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]

The average rate of change for the given function, from x = 8 to x = 5 is

[tex]m=\frac{f(5)-f(8)}{5-8}[/tex]

[tex]m=\frac{4-0}{-3}[/tex]

[tex]m=-\frac{4}{3}[/tex]

Therefore the option A is correct.
