Answer :
1 unit left, because what's inside the bracket with a plus sign goes left and if with a minus sign goes to right.
we know that
The vertex of the graph [tex]y=6x^{2}[/tex] is the point [tex](0,0)[/tex]
The vertex of the graph [tex]y=6(x+1)^{2}[/tex] is the point [tex](-1,0)[/tex]
so
the rule of the translation is
[tex](x,y)------> (x-1,y)[/tex]
That means
one unit to the left
therefore
the answer is the option
1 unit left
