Answer 4

We know it's an oblique asymptote because the function in the numerator has a higher degree than the denominator (ie. x^2 versus just x).

Answer 5

You then have to divide the numerator by the denominator using either long division or synthetic division (whichever one works best for you), and the function you have left if your oblique asymptote. (:

Answer 6

hmm ok lemme try i guess

Answer 7

yeahh idk which to divide

Answer 8

Have you learned how to divide polynomials?

Answer 9

im not clear on it

Answer 11

ok so where to put the x+2

Answer 12

In synthetic division, you divide by the opposite of the variable. So instead of placing '2' into the division square, you write '-2'

Answer 13

so..-2 / -2,3,6?

Answer 15

Yes, and then continue on. The new numbers you get on the bottom are your new coefficients for the oblique asymptote.

Answer 16

Ok I got -2,7,-8

Answer 17

Right, so your oblique asymptote would be y= -2x^2+7x-8

Answer 18

thanks :)

Answer 19

No problem, glad I could help.
