Without using a graphing calculator, determine the following and sketch for: f(x) = x+19x +6x-72 a) the zeros of the function 13 13 b) the degree of the function c) end behaviour of the function d) the y-intercept e) sketch 13 f) the intervals where the function is positive and the intervals where it is negative g) test point 1. For the graph of this polynomial function, determine the following: YA 4 -2 0 x 4 +8 a) the least possible degree b) the sign of the leading coefficient c) the x-intercepts and the factors of the function d) the intervals where the function is positive and the intervals where it is negative 2. 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
