# How do find the vertex and axis of symmetry, and intercepts for a quadratic equation #y= x^2+ 5x - 12#?

##### 1 Answer

Hence vertex

#### Explanation:

So

The minimum value of

If

So the vertex is at

The parabola is vertical, so the axis of symmetry is just the vertical line through the vertex, i.e.

The intercept with the

The intercepts with the

So

So

and

That is the
