Answer
$f(-\frac{1}{2})=\frac{15}{8}$, $(-\frac{1}{2},\frac{15}{8})$
Work Step by Step
Step 1. Use the given coefficients to set up a division as shown in the figure.
Step 2. Perform a synthetic division.
Step 3. Based on the Remainder theorem, we have $f(-\frac{1}{2})=\frac{15}{8}$ and the corresponding point is $(-\frac{1}{2},\frac{15}{8})$
