8-109.

Sketch the parabola *y* = 2*x ^{2} + *6

*x +*4

*by using its intercepts. Homework Help ✎*

Factor this quadratic expression.

Find the *x* and *y*-intercepts.

To find the *x*-intercepts, substitute 0 for *y*, and solve for *x*.

To find the *y*-intercepts, substitute 0 for *x*, and solve for *y*.

To find the vertex, find the point exactly in between the *x*-intercepts and solve for the corresponding *y*-value.
