Help please
i already got the asymptotes
if you'd like me to check the asymptotes I'd be ok with that
Okay so I have 26. vertical x=0 no horizontal 27. vertical x=-4 horizontal y=0 28. vertical x=-2.748 horizontal y=2 29 vertical x=-3 horizontal y=1
I can't see the problem for 29
asymptotes look good for x-intercepts simply take the factors from the numerators and set them equal to zero and find the xvalues
so start by factoring x^2- 12x + 20
26. x intercept (10,0)(2,0) y intercept none 27. x intercept (8,0)(-1,0) y intercept (0,-1/8) 28. x intercept (1,0)(-1-sqrt3/2 , 0) (-1+sqrt3/2 , 0) y intercept (0,1/7) 29. x intercept (1,0) y intercept (0,-1/3)
sorry it took me a while
good, well done
for removable discontinuities you will have to factor the numerator and the denominator and see which produce roots that can be cancelled in the numerator/denominator
okay so
afaik 26 and 27 don't have any removable discontinuities so start with 28
okay so do i factor the num. and denom. separately
yes
then re-write the function in factored form and see if anything cancels out
okay so for example 28 it would be (x-1)(2x^2-2x-1)
I factored the numerator
yeah, I don't think 28 has any removable discontinuities 29 does have one though
um is it infinite discontinuity x=0?
when you factor the numerator and denominator of 29 what do you get?
(x-1)(x+5) and (x+3)(x+5)
so x+5 and cancels out
good, so x = - 5 is the removable discontinuity that's it
thanks !
