Question

State the vertical asymptote of the rational function.

Answer 1

What number do you have to plug in for x to make the bottom part 0?

Answer 2

Assume as follows.
\[x^2 - 4 = 0\\ x^2 = 4\\ x = \pm\sqrt4 = \pm2\]
Therefore f(x) has a vertical asymptote at... \[x = \pm2\]

Answer 3

x = –9, x = 7
x = 9, x = –7
x = 2, x = –2
None

Answer 4

The correct choice is there now select it.

Answer 5

i dont know can you help me?

Answer 6

I stated x = +- 2. Which option corresponds to that?

Answer 7

x=2 x=-2 how did you get that?

Answer 8

A vertical asymptote exists in a rational function where the denominator approaches zero. Take the denominator and find what values of x will cause it to be zero.

Answer 9

when i plug in 2 and -2 on top it gives me -35 than what?

Answer 10

u dont care about the top, u only care about the bottom! whichever set of numbers that gives u zero in the denominator is your vertical asymptote.

Answer 11

oh okay
