Information is given about a polynomial f(x) whose coefficients are real numbers. Find the remaining zeros of f. Degree 5;     zeros: 8, 4 + 5i, -8i

Define the polynomial function of the given graph.  Write in factored form.  f(x) = [jhg]

Must show work on paper for full credit. Find all zeros of the function and write the polynomial as a product of linear factors. (Factored form)       f(x)=x2 + 6x +13 List each zero: [mmy] f(x) = [ffyf] polynomial as a product of linear factors

We add acetic acid to the solution, but it appears nowhere in the reaction formula.  It is therefore likely a ___________.
