# What is the vertex of # y= (x+2)^2-3x^2-4x-4#?

##### 1 Answer

Vertex is at the origin

#### Explanation:

This is a somewhat unusual format for a parabola! Simplify first to see what we are working with..

What does an equation tell us about the parabola?

The standard form is

In

This means that the parabola has not moved to the left or right, nor has it moved up or down, although it is 'upside-down' with a maximum TP.

Its vertex is at the origin

Changing it to vertex form will give

graph{-2x^2 [-4.92, 5.08, -3.86, 1.14]}
