If f(x) is all real numbers then wouldn't this be something like infinite/infinite, infinite/infinite squared, and infinite cubed? Can you do that?

Find lim h(x), if it exists. X -+ 00 f( x) = 6x2+ 2x +6 (a) h(x) = F(x ) lim h(x) = X -+00 (b) h(x) = f(x ) 2 lim h(x) = X - 00 (c) h(x) = F(x ) lim h(x) = X -+ 00
