Question

Identify the oblique asymptote of f(x)=(2x^2+3x+8)/(x+3)

Answer 1

divide, which is kind of a pain,but you can use synthetic division if you know it

Answer 2

I kind of know it

Answer 3

you will get a quotient and a remainder
ignore the remainder, the quotient (which will be a line) is your "oblique" asmptote

Answer 4

you can always cheat if you know how

Answer 5

I don't haha

Answer 6

scroll down to where it says "quotient and remainder"

Answer 7

you will see that is has the quotient at \(2x-3\) so that is your asymptote
but synthetic division is pretty quick and easy

Answer 8

So would the answer be y=2x-3?

Answer 9

yes

Answer 10

Thank you :)
