Answer:
Step-by-step explanation:
We have to see what happens at each graph at the “end” of x axis This means look both to the left and right of the x axis
1) when x approaches -oo, f(x)approaches -oo. When x approaches +oo, f(x) approaches +oo
2) when x approaches -oo, f(x) approaches +oo. When x approaches +oo, f(x) approaches +oo
3) when x approaches -oo, f(x) approaches -oo. When x approaches +oo, f(x) approaches -oo
4) when x approaches -oo, f(x) approaches -oo. When x approaches +oo, f(x) approaches +oo
