Help me please i really need help friends :(

When x approaches infinity, the graph goes to 0, because the x² from denominator approaches infinity faster than (2x).

Or you can apply l'Hopital formula:

Limit of graph =lim[(2x)'/(1-x²)']=lim[2/(-2x)]=0

answer: second option, graph goes to 0

the correct answer is b.

this is because an open circle means < or > & since the line goes left it is < -3.

the next one has a filled circle so it can only be ≥ or ≤ and since the line goes right from 1 it is ≥ 1

hope that
