Question

whats the domain of x^4-1

Answer 1

R

Answer 2

all polynomials have domain of All Real num

the restrictions come when its a fraction or square root

Answer 3

& x^3 is the numerator so what would the horizontal asymptote be?

Answer 4

umm you might want to add that bit at the beginning

Answer 5

x^3/x^4-1

Answer 6

1 is the asymptote

Answer 7

what is the horizontal asymptote

Answer 8

did you look at a graph?

Answer 9

i shall state the rule again for horizontal asymptotes...maybe you should write it down

if degree of bottom > degree of top, then horizonatl asymptote is y=0

Answer 10

yes it has no vertical asymptote and the horizontal asymptote is -1
