Find the

*x*- and*y*-intercepts.To find the

*y*-intercept, substitute 0 for*x*.*y*= 0 + 0 + 1To 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) andWhere 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.Find the coordinates of the vertex.

Substitute the

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