(3,0)(3,0).

Explanation:

The Graph GG of the given function ff is,

G_f={(x ,y)| y=f(x)=2x-6} sub RR^2.

Recall that, X"-axis "= G_X={(x,y)|y=0} sub RR^2.

So, to find the point of intersection of G_f and G_X, i.e., G_fnnG_X, we let, y=0" in "y=2x-6," giving, "x=3.

We readily have, y=0.

Hence, G_fnnG_X={(3,0)}.
