The average rate of change of the graphed quadratic function is its slope
The average rate of change over the interval is 2
How to determine the average rate of change?
The interval is given as:
x = 0 to x = 3
From the graph, we have:
When x = 0, f(0) = -6
When x = 3, f(3) = 0
The average rate of change is calculated as:
[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]
So, we have:
[tex]m = \frac{0 - -6}{3 - 0}[/tex]
Evaluate the quotient
[tex]m= 2[/tex]
Hence, the average rate of change over the interval is 2
