Practice problem
Based on the table below, what is f(x)f(x)f(x)? x−2−1012f(x)63236\begin{array}{|l|l|} \hline x&-2&-1&0&1&2\\ \hline f(x)&6&3&2&3&6\\ \hline \end{array}xf(x)−26−13021326
f(x)=x+1f(x)=x+1f(x)=x+1
f(x)=x2f(x)=x^{2}f(x)=x2
f(x)=x2−1f(x)=x^{2}-1f(x)=x2−1
f(x)=x2+2f(x)=x^{2}+2f(x)=x2+2
Type a concept, like “slope” or “photosynthesis”.
