The vertical asymptote is determined by equating the denominator to zero and solve for x.
The equation of the vertical asymptote is
The numerator has the same degree as the denominator.
The equation of the horizontal asymptote is the coefficient of the leading term in the numerator expressed over the coefficient of the leading term in the denominator.
the two numbers that are across from each other you multiply and then divide by the third number. Just wanted to make it more easy for you. Plug in the formula above into a calculator and bam!
