  1. Find the x- and y-intercepts.

    To find the y-intercept, substitute 0 for x.

    y = 0 + 0 + 1

    To find the x-intercepts, factor the equation and substitute 0 for y.

    The y-intercept is (0, 1) and the x-intercepts are (−1, 0) and 

  2. Where is the line of symmetry of this parabola? Write its equation.

    To find the line of symmetry, average the x-values of the
    x-intercepts.

  3. Find the coordinates of the vertex.

    Substitute the x-value for the line of symmetry into the equation.
