Vertical 1)Vertical Asymptotes 2) Horizontal Asymptotes 3) Slant Asymptotes Asymptotes Sec 4.5 SUMMARY OF CURVE SKETCHING Horizontal Slant or Oblique called a slant asymptote because the vertical distance between the curve and the line approaches 0. For rational functions, slant asymptotes occur when the degree of the numerator is one more than the degree of the denominator. In such a case the equation of the slant asymptote can be found by long division as in the following
