The average rate of change over the interval [2,4] can be calculated by subtracting the initial value from the final value and then dividing by the change in x.
f(4) = -4
f(2) = 8
(-4 - 8) / (4 - 2) = -12 / 2 = -6
Therefore, the average rate of change over the interval [2,4] is -6.
Calculate the average rate of change over the interval [2,4] given the function table for f(x)=−x2+12.
