    find vertex and intercepts for each parabola and sketch its graph
    2
    y= -x -3x-2

    Solution. As

    , we know that the vertex is at (-3/2, ¼).

    Let x=0, we get
    y=-2
    So, the y-intercept is at (0, -2).

    Let y=0, we have

    So,
    x=-1 or x=-2.

    Hence, two x-intercepts are (-1, 0) and (-2,0).

    See a sketch of the graph below.
