Find the axis of symmetry and the vertex of the graph of y = 3x2 + 2x.
The axis of symmetry is x=
and the vertex is

Step-by-step explanation:

Finding Vertex

Given

The vertex of an up-down facing parabola of the form

The Parabola params are:

            ∵  

Therefore the parabola vertex is:

Finding symmetry

For a parabola in standard form

the axis of symmetry is the vertical line that goes through the vertex

Therefore,

the answer would be c:   ax + b = ax + c
