Answer:
Interval [b,c] and interval [c,d]
Step-by-step explanation:
a(-5,0)
b(-1,2)
c(4,3)
d(11,4)
The average rate of change is the the total rise over the total run.
The Rise means the vertical increase and the Run means horizontal incease.
For interval [a,b]
rate of change is [tex]\dfrac{2-0}{-1-(-5)}=\dfrac{2}{4}=\dfrac{1}{2}[/tex]
For [b,c]
[tex]\frac{3-2}{4-(-1)}=\frac{1}{5}[/tex]
For [c,d]
[tex]\dfrac{4-3}{11-4}=\dfrac{1}{7}[/tex]
