What is the average rate of change for this quadratic function for the interval from x=1 to x=3?
Accepted Solution
A:
Answer:The average rate of change is [tex]-4[/tex]Step-by-step explanation:we know that
the average rate of change using the graph is equal to
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
In this problem we have
[tex]f(a)=f(1)=0[/tex] Β [tex]f(b)=f(3)=-8[/tex]
[tex]a=1[/tex]
[tex]b=3[/tex]
Substitute
[tex]\frac{-8-0}{3-1}=-4[/tex]
