Question

Please help(:
Find the horizontal asymptote of the graph of
6x^2 + 5x + 9 / 7x^2 -x + 9

Answer 1

Take the limit as x goes to infinity....the result would be inf/inf (an indeterminate form)

What you would do is this

derivative of numerator/derivative of denominator

Answer 2

@Jlastino not sure :/

Answer 3

oh are you taking up calculus?

Answer 4

@Jlastino algebra 2

Answer 5

ok so what you will do is divide everything by the variable with highest exponent (x^2)

Answer 6

@Jlastino ok cool then what?

Answer 7

can you show me the resulting equation?

Answer 8

I just got y=6/7 as my answer because im looking at my book also for help

Answer 9

Or you could just look at the lead term of num and dem.

if:
num < dem, y = 0
num = dem, y = num/dem
num > dem, no horizontal asymptote, but oblique

Answer 10

yeah that's it

Answer 11

@Jlastino i'm right? 6/7?
