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.
(2x + 1)(x + 1) = 0
The y-intercept is (0, 1) and the x-intercepts are (−1, 0) and
To find the line of symmetry, average the x values of the x-intercepts.
Substitute the x value for the line of symmetry into the equation.
