Factoring and Graphing Polynomial Functions
Which of the following is NOT considered when determining the end behavior? Degree Number of terms Leading Coefficient What is the end behavior of the polynomial function f(x) = -3x5 + 6x3 - 12x Up Up Down Down What is the y-intercept of the function f(x) = 3x3 + 7x2 - 9x - 8 (0, 3) (0, 7) (0, -9) (0, -8) Which of the following is NOT an x-intercept of the polynomial function f(x) = x3 - 5x2 - 9x + 45 (5, 0) (3, 0) (9, 0) (-3, 0) Which of the following is NOT an x-intercept of the polynomial function f(x) = x4 - 7x3 - 18x2 (7, 0) (0, 0) (9, 0) (-2, 0) Use the coordinate plane below to graph the polynomial functionf(x) = -x3 - 4x2 +x +4 In order to receive full credit, the end behavior must be clearly represented. In order to receive full credit, the x-intercepts and y-intercept must be clearly graphed. Which of the following is true about the polynomial functionf(x) = x3 + 3x2 - 9x - 27 It has a y-intercept at (0, -9). The end behavior is considered down The function makes a "u turn" at (3, 0) The function makes a "u turn" at (-3, 0)
