#### Answer:

VA:

HA:

#### Explanation:

(VA) Vertical Asymptote: Set the denominator equal to zero:

(HA) Horizontal Asymptote: Divide the coefficients of the x values:

#### Answer:

#### Explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote.

#"solve "x-5=0rArrx=5" is the asymptote"#

#"horizontal asymptotes occur as"#

#lim_(xto+-oo),f(x)toc " ( a constant)"#

#"divide terms on numerator/denominator by x"#

#f(x)=(x/x)/(x/x-5/x)=1/(1-5/x)#

#"as "xto+-oo,f(x)to1/(1-0)#

#rArry=1" is the asymptote"#
