Complete the square to find the vertex, axis of symmetry, etc.

#### Explanation:

So

This is in vertex form,

allowing us to tell that the vertex is at

and the axis of symmetry is

The intersection with the

The intersections with the

Add

Multiply both sides by

Hence

So the intersections with the

graph{3/2x^2-3x-5/2 [-10, 10, -5, 5]}
