Answer by Earlsdon(6294) (Show Source): You can put this solution on YOUR website!
You can find the x-coordinate of the vertex of this parabola from:
= 2
The y-coordinate is found by substituting this value of x (2) into the quadratic equation and solving for y:

The vertex is at (2, -3)
Then you could find the x-intercepts (there will be two of 'em) by letting y = 0 and solving for the roots.
Use the quadratic formula to solve:

and
Here's what the graph will look like:
