Step-by-step explanation:
Given the function 
The average rate of change of the function h(x) over the interval
can be calculated using formula

In your case,

so the average rate of change is

Step-by-step explanation:
x² + 3x + 2
x² + x + 2x + 2 because 1+2=3 and 2×1=2
By taking out common terms, we get
x(x+1)+2(x+1)
(x+1)(x+2)
