    the maximum or minimum occurs at the vertex so you need to find the vertex of this do you know how to find the coordinate of the vertex

    Well the x coordinate of the vertex is given by x = -b/2a Once you find the x coordinate, then plug this into the original equation to find the y value which is the maximum value
