please help with this calculus question?

OpenStudy (anonymous):

OpenStudy (anonymous):

x = 1 is an asymptote of f x = -1 is NOT an asymptote of f f has a root at x = 2 the axis is an asymptote of f the y-axis is an asymptote of f

OpenStudy (anonymous):

@abb0t can you please help on this one?

OpenStudy (anonymous):

anyone?

OpenStudy (anonymous):

\[\frac{3x(x^2-x-2)}{2x(x^4-1)}\] is the first step

OpenStudy (anonymous):

then \[\frac{3x(x-2)(x+1)}{2x(x^2+1)(x+1)(x-1)}\] is the second

OpenStudy (anonymous):

ooops scratch that

OpenStudy (anonymous):

there is not a common factor of \(x-1\) top and bottom, so \(x=1\) IS a vertical asymptote

OpenStudy (anonymous):

\(f\) has a root of \(2\) for sure, because of the factor of \(x-2\) in the numerator

OpenStudy (anonymous):

but that would give me two choices and i can only choose one

OpenStudy (anonymous):

which one would work?

OpenStudy (anonymous):

the \(x\) axis IS an asymptote, as the degree fo the numerator is smaller than the degree of the denominator

OpenStudy (anonymous):

it says "which is NOT true"

OpenStudy (anonymous):

oh right im sorry. im looking for the one that is NOT true

OpenStudy (anonymous):

right :)

OpenStudy (anonymous):

ok so that means that x=-1 is NOT true right?

OpenStudy (anonymous):

i think the last one is not true

OpenStudy (jdoe0001):

x = -1 is NOT an asymptote of f <-- is true, since it's negated already

OpenStudy (anonymous):

the y axis?

OpenStudy (anonymous):

right lets check

OpenStudy (anonymous):

but isn't (x+1) mean that -1 IS an asymptote of f?

OpenStudy (anonymous):

one at a time x = 1 is an asymptote of f this is TRUE

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

x = -1 is NOT an asymptote of f this is TRUE

OpenStudy (anonymous):

f has a root of x=2 i\is TRUE

OpenStudy (anonymous):

f has a root at x = 2 is also TRUE

OpenStudy (anonymous):

Right

OpenStudy (anonymous):

the axis is an asymptote of f also TRUE

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

got it

OpenStudy (anonymous):

thank you!

@satellite73 one more please?
