Parentheses first, 72-63 is 9 next multiply by 4 which is 36 the you’ll divide by 3 now you have 12 so multiply that by 6 and you get 72. Just a hint, another way to write that without using the multiply or the divided would be 6[4(72-63)/3] but either way you want is fine. Hope this helped :)

What is the average rate of change of f(x), represented by the table of values, over the interval [-3, 2]?

maksim [4K]

You would select the points with the x-values -3 and 2 and use the slope formula:
(-3, -36) and (2,4)
$m= \frac{y_2-y_1}{x_2-x_1}$ ← slope formula
x1 = -3 y1 = -36 and x2 = 2 y2 = 4

$m= \frac{4--36}{2--3} = \frac{40}{5} =8$
