What is the average rate of change of h over the interval {1,2}?
kondaur [170]

Answer:

3

Step-by-step explanation:

The average rate of change of h(x) in the closed interval [ a, b ] is

\frac{h(b)-h(a)}{b-a}

Here [ a, b ] = [ 1, 2 ] , then

h(b) = h(2) = 0 ← from table for x = 2

h(a) = h(1) = - 3 ← from table for x = 1 , then

average rate of change = \frac{0-(-3)}{2-1} = \frac{0+3}{1} = 3
