What is the equation of the graph below?

a graph shows a parabola that opens up with a vertex at three comma negative two.

Step-by-step explanation:

Given vertex of parabola

Where is the vertex.

Also parabola opens up.

The equation of parabola with vertex

If parabola opens up.

parabola opens down.

As the parabola opens up the value of will greater than zero.

Plugging vertex of parabola in equation

Let us plug

The equation will be

bottom left

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.
