To sketch the graph of the inequality y < x 2 + 10 x + 9 , first find the roots, vertex, and y-intercept of the equation y = x 2 + 10 x + 9 . The parabola opens upwards, with the boundaries at x-intercepts (-1, 0) and (-9, 0), and the region below the parabola should be shaded to represent the inequality. Use a dashed line for the parabola to indicate that it's not included in the solution.
