How to Tell That a Function Has a Horizontal Asymptote?

Same degree in numerator & denominator—>numerator coefficient/denominator coefficient

Ex: 2x+3/x; H.A.= y=2

How to Tell That a Function Has a Horizontal Asymptote of 0?

Bottom Heavy—>H.A.=0

Ex: x+2/x³; H.A.= y=0

How to Tell That a Function Has an Oblique/Slant Asymptote and No Horizontal Asymptote?

Top Heavy—>S.A.

Ex: x³-3/x²; H.A.=non-existent.

How to Tell That a Function Has a Vertical Asymptote?

Non-cancelable variable in denominator

Ex: x/x-2; V.A.= x=2

Slope of normal line (as opposed to tangent)

- reciprocal of slope of tangent line
