Answer:

Step-by-step explanation:

Given the table

$\begin{array}{ccccc}x&0&1&2&3\\ \\y&-6&-5&2&21\end{array}$

The change in x is

$1-0=2-1=3-2=1$

The change in y is

$-5-(-6)=1\\ \\2-(-5)=7\\ \\21-2=19$

Since for the same change in x, the change in y is different, given table represents nonlinear function.
