Find the real zeros of the given polynomial and their corresponding multiplicities. Use this information, along with a sign chart, to provide a rough sketch of the graph of the polynomial. f (x) = x(x - 3)2(x +4) 6.) For the following equation, write the equation in standard form (f(x)=a(x-h)2 + k) using completing the square, find the vertex and identify if it is minimum or maximum, identify the domain and range, determine where the function is increasing/decreasing, and identify where f(x)
