Question
Evaluate each expression based on the following table.$$\begin{array}{|c|c|c|c|c|c|c|c|}\hline x & -3 & -2 & -1 & 0 & 1 & 2 & 3 \\\hline f(x) & 1 & 2 & 4 & 2 & -1 & -0.5 & 0.25 \\\hline\end{array}$$ a. $f(1)-f(-1)$b. $f(1) f(-2)$c. $3 f(-2)$
Step 1
From the table, we can see that $f(1) = -1$ and $f(-1) = 4$. Show more…
