2-57.

Find the *x*- and *y*-intercepts and the equation of the line of symmetry for the graph of *y* = *x*^{2} + 6*x* + 8. Homework Help ✎

Substitute 0 for *y* and solve to find the *x*-intercepts.

Substitute 0 for *x* to find the *y*-intercept.

Start to sketch the graph by locating the *x*-intercepts and use the location of the *x*-intercepts to figure out where the axis of symmetry must be.

The *y*-intercept is (0, 8), the *x*-intercepts are (−2, 0) and (−4, 0), and the line of symmetry is *x* = −3.
