State the vertical asymptote of the rational function. (2 points)

f(x) = quantity x minus nine times quantity x plus seven divided by quantity x squared minus four.

x = -9, x = 7

x = 9, x = -7

x = 2, x = -2

None

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
