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
