Answer:
D
Step-by-step explanation:
Given the table
[tex]\begin{array}{ccccc}x&0&1&2&3\\ \\y&-6&-5&2&21\end{array}[/tex]
The change in x is
[tex]1-0=2-1=3-2=1[/tex]
The change in y is
[tex]-5-(-6)=1\\ \\2-(-5)=7\\ \\21-2=19[/tex]
Since for the same change in x, the change in y is different, given table represents nonlinear function.
