A. y = 2 B. x = 2 C. y = -5 D. y = 2/5

3. Jusaquikie

take the limit as x approches infinity and negative infinity

4. iheartfood

idk how to

5. Jusaquikie

ok we are going to make all out x's infinity

6. Jusaquikie

then we get $2\infty /\infty+5$

7. Jusaquikie

the +5 is going to be meaning less next to infinity so we throw it away

8. iheartfood

kk so we end up with 2/5 ?

9. Jusaquikie

so we are left with $2\infty/\infty$ then we cancle the infinity cause it is on bith the top and bottom we are left with 2

10. Jusaquikie

try to think of infinity as a large number not a consept, how big is 5 compared to 1,000,000?

11. iheartfood

so I'm left with 2?

12. Jusaquikie

it is insignifigant, so we just throw it away, the 2 is actualy saying infinity+infinity so that is significant

13. Jusaquikie

so think of it as simplifying the fraction 2,000,000 / 1,000,000

14. Jusaquikie

we factor out the million for top and bottom and we are left with 2/1

15. iheartfood

so my answer is A. y = 2???

16. Jusaquikie

yes

kk thanks :)
