## Given the function f = x³ - 6x² + 16x 1. Apply the Rule of Signs and determine the number of possible positive x-intercepts. Zor O 2. Apply the cubic formula. ± √b²-3ac 3a a. Find the x and y coordinates of the point of inflection. X=-b За X = = 3(1) ± √-+6²-3 (1) (16)--2 ± √ 3(1) b. Find the slope of the line that passes through the point of inflection. c. Interpret the slope and determine if f is increasing or decreasing at the point of inflection. d. Use the Solver functionality of the TI and find all positive zeros. e. List all real zeros. 3. Use the formula from algebra and find the x coordinate of the vertex of the equation y = 3x² 12x + 16. I r 4. Find the y value of the vertex of y = 3x² - 12x + 16.
