Answer:

3

Step-by-step explanation:

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

[tex]\frac{h(b)-h(a)}{b-a}[/tex]

Here [ a, b ] = [ 1, 2 ], then from the table

h(b) = h(2) = 0

h(a) = h(1) = - 3 , then

average rate of change = [tex]\frac{0-(-3)}{2-1}[/tex] = [tex]\frac{3}{1}[/tex] = 3
