# How do I find the vertex, axis of symmetry, y-intercept, x-intercept, domain and range of #y= -x^2-8x+10#?

##### 1 Answer

Vertex:

Axis of symmetry:

y-intercept:

x-intercepts:

Domain:

Range:

#### Explanation:

**Vertex**

Re-writing

with vertex at

**Axis of Symmetry**

Any parabola in the form

In this case

**y-intercept**

The y-intercept is the value of

**x-intercepts**

The x-intercepts are the values of

**Domain**

**Range**

Since a parabolic equation with a negative coefficient for the

The Range is
