DO you have any idea

3. ShotGunGirl

Not not really. I stink at this stuff. Sorry :(

4. lala2

oh ok

5. lala2

@Rainbowpower

6. lala2

Do you know?

7. Rainbowpower

yep hold on im working the problem out :)

8. Rainbowpower

Factoring polynomials never goes away. You have to factor numerator and denominator. x^3+x^2-4x-4 can be factored "by grouping" as X^3+x^2-4x-4=(x^3-4x)+(x^2-4)+(x^2-4)=(x+1)*(x^2-4) It can be factored further because the difference of squares x^2-4=x^2-2^2 factors as (x-2)*(x+2) x^2+2x-3=(x+3)*(x-1)

putting it all together:

10. Rainbowpower

oh and the function is not defined (it does not exist) for x=1 and for x=-3 because the denominator is zero for those values of x .

11. Rainbowpower

Hope this helps :) have a colorful day

@lala2

13. lala2

Sorry my computer wasnt working

14. lala2

so would the answer be x=1 and x=-3

15. lala2

@Rainbowpower ??

x=1 and x=-3 would result in a division by zero, and as you know that is a "no-no" and would result in a discontinuity.

Yes, that is what the problem is seeking.

19. lala2

And what about this one Describe the vertical asymptote and hole for the graph of x^2+x-6/ x^2-9

20. lala2

21. lala2

????

a division by zero would occur a x=3

23. lala2

so is it x=3 and x=-3

I am not sure what occurs when x=-3 but x=3 and x=-3 is probably your best choice.

25. lala2

oh ok thanks... you know that question i sent you

26. lala2

and you asked if there was a slope

27. lala2

here is the graph

|dw:1360084607949:dw|

29. lala2

30. lala2

what is that...

31. lala2

did you get the graph

32. lala2

I believe the 3rd choice may be the best, still not sure about the

34. lala2

36. lala2

oh ok... and what about the question with the graph

I also don't know the answer to the link graph. Not too much help today.

Regarding the graph, you do have a y intercept at x=-3. It is a function as a vertical line will not intercept the y values twice. It is a non-linear function.

It is a direct variation y=3x

40. lala2

it want me to write an equation

41. lala2

and I provided one for you. y=3x

I gotta run for now (lunch)

44. lala2

oh ok thanks!
