# How do find the vertex and axis of symmetry for a quadratic equation #y=-2x^2-8x+3#?

##### 1 Answer

See the explanation below.

#### Explanation:

General equation for the quadratic formula:

The graph of a quadratic equation is a parabola.The axis of symmetry is the vertical line that separates the parabola into two equal halves.The point on the x-axis where the vertical axis is placed is determined by the formula

Substitute

The vertex of a parabola is the point where the parabola crosses its axis of symmetry. Vertex
