Select the correct answer A parabola is represented by the equation y = x2 + 6x − 17. The x-intercepts of the parabola are: a. (-8.20,0) b. (-8.10,0) c. (-8.09,0) d. (-8.07,0) AND a. (2.20,0) b. (2.10,0) c. (2.09,0) d. (2.07,0) The y-intercept of the parabola is a. (0,-34) b. (0,-17) c. (0,-11) d. (0,8.50) (If necessary, round your answers to the nearest hundredth.)

    the x-intercept when y = 0 set the function = 0 and factor to find the x-values the y-intercept when x = 0 substitute x = 0 in the function and compute y to the nearest hundredth means to 2 decimal places

    ok you need to read my response and then you would do the last step x = -5.09 -3 and x = +5.09-3 what are the final x values? we know that y = 0

    when x = 0 x^2 + 6x -17 means (0)^2 + 6(0) - 17 =
