1 Answer

Nov 3, 2015

The axis of symmetry is #x=-1#.

Explanation:

#y=3x^2+6x+2# is a quadratic formula In the form #ax^2+bx+c#, where #a=3, b=6, and c=2#.

The equation for calculating the axis of symmetry for a quadratic equation is #x=(-b)/(2a)#.

#x=(-6)/(2*3)=#

#x=(-6)/6=-1#

The axis of symmetry is #x=-1#.
