Determine the equation with least degree for the polynomial function: a quintic function with zeros -2(multiplicity 3) and 4 (multiplicity 2), and y-intercept = = -32 3. The graph of y=x3 is transformed to obtain the graph of y=-2(4(x+1))-5. Describe each of the transformations and then copy and complete the table. Sketch the function. 10 y=x (-2, -8) (-1,-1) (0, 0) (1, 1) (2,8) y=-2(4(x+1))3-5 4.
