F(x) = 22 +10 What is the average rate of change of f over the interval (-2,-1]?

Step-by-step explanation:

The average rate of change of function fff over the interval a\leq x\leq ba≤x≤ba, is less than or equal to, x, is less than or equal to, b is given by this expression:

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

b−a

f(b)−f(a)

start fraction, f, left parenthesis, b, right parenthesis, minus, f, left parenthesis, a, right parenthesis, divided by, b, minus, a, end fraction

It is a measure of how much the function changed per unit, on average, over that interval.

It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.

The r value is a number between -1 and +1.

For a negative value, the closer to -1 it would be a strong negative, if it is closer to 0, it would be a strong negative.

-0.31 is closer to 0 than -1, so it would have a strong negative association.
