Solution
Step 1:
To determine average rate of change from x = 2 to x = 5 .
Determine the corresponding values of y.
Step 2:
Find the rate of change from (2, -1) and (5 , 2)
[tex]\begin{gathered} Avearge\text{ rate of change = }\frac{2\text{ - \lparen-1\rparen}}{5\text{ - 2}} \\ =\text{ }\frac{2\text{ + 1}}{3} \\ =\text{ }\frac{3}{3} \\ =\text{ 1} \end{gathered}[/tex]
Final answer
The average rate of change = 1
