8-64.

Sketch the parabola $y=2x^2+6x+4$ by using its intercepts.

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.
