# How do you find the axis of symmetry and vertex point of the function: #y = -x^2 - 8x + 10#?

##### 1 Answer

The axis of symmetry is

The vertex is

#### Explanation:

**Axis of Symmetry**

The axis of symmetry is the imaginary vertical line that divides the parabola into two equal halves.

The formula for the axis of symmetry is

The axis of symmetry is

This is also the

**Vertex**

The vertex is the maximum or minimum point of the parabola. Since

Since we know that

The vertex is

graph{y=-x^2-8x+10 [-18.16, 13.86, 14.09, 30.11]}
