Question

Which of the following is false for

Answer 1

A. The y-axis is not an asymptote of f(x).
B. The x-axis is an asymptote of f(x).
C. x = –1 is not an asymptote of f(x).
D. x = 1 is an asymptote of f(x)

Answer 3

what do you have so far?

Answer 4

is it D?

Answer 5

why do you think it's D?

Answer 6

\[limf(x){x \rightarrow \infty}=0\]
\[f'(x) = −\frac{10\,{x}^{5}−15\,{x}^{4}−20\,{x}^{3}+10\,x−5}{{x}^{8}−2\,{x}^{4}+1}\]
\[lim f'(x){x \rightarrow \infty}=0\]
so, f(x), x infinite is decreasing (f'(x) negative arround infinite)
B.

Answer 7

okay i read y = 1 for some reason, iv graphed it and the table says x=1,0, and -1 are DNE

Answer 8

is it C then

Answer 9

yeah because x = -1 is an asymptote

saying `x = –1 is not an asymptote of f(x).` is false

Answer 10

thank you very mucuh.
