If there is more than one x-intercept, separate them with commas.Answer by spacesurfer(12)   (Show Source): You can put this solution on YOUR website!This is a simple quadratic equation to find the x-intercepts: The solutions are x = 4 or -6 and these are the x-intercepts. The vertex can be found by finding the derivative and setting it equal to 0 If , then , and , then x = -1 and f(-1) = -25. Hence, the vertex is (-1, -25)
