Graph the function in a viewing window that will allow you to use a calculator to approximate (a) the coordinates of the vertex and (b) the x-intercepts. y= -0.33x+3x+0.18 (a) The vertex is (2.62,2.45) (Type an ordered pair. Round the final answer to the nearest hundredth as needed. Round all intermediate answers to two decimal places as needed.) Determine a reasonable viewing rectangle on your graphing utility and use it to graph the quadratic function. Choose the correct graph below. A. [-20,20,4] by [-30,30,5] B. C. D. E G E [-20,20,4] by [-30,30,5] [-20,20,4] by [-5,30,5] [-20,20,4] by [-30,30,5] (b) The x-intercept(s) is/are (Type an ordered pair. Use a comma to separate answers as needed. Round each coordinate to the nearest hundredth as needed.)
