Solved Example on Asymptote

Ques: Find the vertical asymptote of the graph of the function example of Asymptote .

Choices:

A. x = - 1
B. x = 1
C. x = 0
D. x = 2
Correct Answer: B

Solution:

Step 1:example of Asymptote is clearly discontinuous at x = 1.
Step 2: example of AsymptoteIf then the line x = c, is the vertical asymptote. [Definition.]
Step 3: example of Asymptote [For the vertical asymptote.]
Step 4: example of Asymptote [Numerator is positive, denominator is a very small positive number.]
Step 5: example of Asymptote [For the vertical asymptote.]
Step 6: example of Asymptote[Numerator is positive, denominator is a very small negative number.]
Step 7: So, x = 1 is the vertical asymptote of the curve f (x).
