Question

Consider the table representing a rational function.

Which equation could represent a vertical asymptote of the graph of the function?
A. x = 0
B. y = 0
C. x = -1
D. y = -1

Answer 1

C

Explanation:

a vertical asymptote is a vertical line with equation

x = c ( c is the value of the x- coordinates the line passes through )

a vertical asymptote is derived from the denominator of a rational function and causes the function to be undefined.

from the table f(x) is undefined for x = - 1 , then

equation of vertical asymptote is x = - 1
