1-27.

Why does this graph have a vertical asymptote? What is the equation of that asymptote?

Consider your answer to 1-26(d).

Vertical asymptotes are lines with undefined slopes. Their equations are of the form:

whereis a constant.State the equation of the horizontal asymptote.

Consider the horizontal lines that you found in problem 1-22(b).

Horizontal asymptotes are lines with

slope. Their equations are of the form: or, whereis some constant.Alter the equation
