# How do you find the vertex and axis of symmetry of # f(x)= 3x^2 + 12x + 1#?

##### 1 Answer

This is a quadratic equation of a parabola (the squared term gives it away)

#y = ax^2+bx+c#

the vertex is located where

this occurs where

substitute into the equation to figure out the y coordinate of the vertex.

The axis of symmetry is the vertical line passing through the vertex which is
