1) Examining the table we can write the following calculating the Average rate of change, applying the formula:
[tex]\Delta=\frac{f(b)-f(a)}{b-a}[/tex]
[0,5}
[tex]\Delta=\frac{28-3}{5-0}=\frac{25}{5}=5[/tex]
[-3,3]
[tex]\Delta=\frac{f(3)-f(-3)}{3+3}=\frac{12-12}{6}=0[/tex]
[-5,3]
[tex]\Delta=\frac{f(3)-f(-5)}{3-(-5)}=\frac{12-28}{8}=\frac{-16}{8}=-2[/tex]
[-3,5]
[tex]\Delta=\frac{f(5)-f(-3)}{5-(-3)}=\frac{28-12}{8}=\frac{16}{8}=2[/tex]
2) Hence the answer in order is
5,0,-2,2
