2. Use the given information about a polynomial function $f(x)$. (a) (5 points) Derive $f(x)$ in factored form having degree 4; zeros: 3, 2, and - 1; leading coefficient of 1/2. (Note: there is no benefit to expand out the factored form of $f(x)$ for this question. Do not include the expanded form of $f(x) .)$ (b) (5 points) Graph your derived function, scale, resize, and label appropriately. CS.VS. 1396
