Practice problem
Based on the table below, what is f(x)f(x)f(x)? x12345f(x)4681012\begin{array}{|l|l|} \hline x&1&2&3&4&5\\ \hline f(x)&4&6&8&10&12\\ \hline \end{array}xf(x)142638410512
f(x)=x+1f(x)=x+1f(x)=x+1
f(x)=x+3f(x)=x+3f(x)=x+3
f(x)=2x+2f(x)=2x+2f(x)=2x+2
f(x)=4xf(x)=4xf(x)=4x
Type a concept, like “slope” or “photosynthesis”.
