6. Determine the degree, the leading coefficient, the constant, and the y-intercept for each of the following. a) P(x) =4x3 +(3x?)? -2x+7 (2 marks) b) P(x) =4(2x-1)' -(x+3) (2 marks) c) P(x) = (x+3)?(x-2)(x+4) (2 marks) 7. Sketch the shape of the graph of each function with the given zeros. Assume a, >0. Assume minimum degree. (6 marks) a) 0, - 2, 3 b ) 2 (multiplicity 2) c) 1 (multiplicity 2), 3, 5
