Question

Identify the oblique asymptote of f(x) = quantity x squared minus 4 x plus 8 over quantity x plus 2.
HELPPP

Answer 1

The oblique asymptote will come from the long division

\[\large \frac{x^2 - 4x + 8}{x + 2}\]

Answer 2

THANKS SO MUCH

Answer 3

No problem :)

Answer 8

Identify the horizontal asymptote of f(x) = quantity x squared plus 5 x minus 3 over quantity 4 x minus 1.

Answer 9

Horizontal asymptotes happen when we see what the function equals when we let x go to infinity

Answer 10

so

\[\large \frac{x^2 + 5x - 3}{4x - 1}\]

If we plug in infinity here for 'x' we would essentially have

\[\large \frac{\infty^2}{\infty} = \infty\]

Answer 11

Now we dont say this has a horizontal asymptote of infinity...we just say it doesn't have one

Answer 12

oh. okay great thanks so much, i really appreciate it

Answer 13

Anytime!

Answer 14

so for oblique asymptotes we do long division?

Answer 15

Right

Oblique = long division
Horizontal = plug in infinity for 'x' and simplify
Vertical = See what makes the denominator = 0

Answer 16

okay i sorta get it now
thanks thanks loads

Answer 20

What is the discontinuity of the function f(x) = the quantity of x squared minus 4 x minus 12, all over x plus 2?
