It will be 2 since the lowest value 3x+6 reaches is zero, since absolute values are never negative. And the vertex of such an absolute value function occurs on the axis of symmetry, which is where the absolute value part is zero.

y=3x+62, for x <2 and y =3x62 for x>2 use this to draw the graph and get the vertex

it can be y=(3x+6)2 or y=3x62 then y=3x+4 or y=3x8
