yep hold on im working the problem out :)

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)

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 .

Hope this helps :) have a colorful day

Sorry my computer wasnt working
anonymous
  • anonymous
so would the answer be x=1 and x=-3
anonymous
  • anonymous
@Rainbowpower ??
radar
  • radar
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.
radar
  • radar
Yes, that is what the problem is seeking.
anonymous
  • anonymous
so that is the answer

And what about this one Describe the vertical asymptote and hole for the graph of x^2+x-6/ x^2-9
anonymous
  • anonymous
@radar ??
anonymous
  • anonymous
????
radar
  • radar
a division by zero would occur a x=3
anonymous
  • anonymous
so is it x=3 and x=-3
radar
  • radar
I am not sure what occurs when x=-3 but x=3 and x=-3 is probably your best choice.
anonymous
  • anonymous
oh ok thanks... you know that question i sent you
anonymous
  • anonymous
and you asked if there was a slope
anonymous
  • anonymous
here is the graph

what is that...
anonymous
  • anonymous
did you get the graph
anonymous
  • anonymous
@radar ?
radar
  • radar
I believe the 3rd choice may be the best, still not sure about the
anonymous
  • anonymous
about what?
radar
  • radar
about the x = -3
anonymous
  • anonymous
oh ok... and what about the question with the graph
radar
  • radar
I also don't know the answer to the link graph. Not too much help today.
radar
  • radar
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.
radar
  • radar
It is a direct variation y=3x
anonymous
  • anonymous
it want me to write an equation
anonymous
  • anonymous
its asking for an equation
radar
  • radar
and I provided one for you. y=3x
radar

I gotta run for now (lunch)
anonymous
  • anonymous
oh ok thanks!
