Question

Which function has the following characteristics?

A vertical asymptote at x = 3
A horizontal asymptote at y = 2
Domain: {x≠±3

A. y= 2x-8/x-3
B. y=x^2-9/x^2-4
C. y=2x^2-18/x^2-4
D. y=2x^2-8/x^2-9

Answer 1

It must be D since only this function;s denomitor will go to zero if we plug in three, and its has a horizontal asymptote at 2

Answer 2

Plus the domain of this funtion is x cannot = plus or minus 3

Answer 3

any questions?
