Verticsl asymptote at
Horizontal asymptote
Explanation:
You can find the vertical asymptote if you equate the denominator to 0
Horizontal asymptote is at y=0 as the highest degree ( power on the x) on the numerator is less than the highest degree on the denominator
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 values that x cannot be and"#
#"if the numerator is non-zero for these values then they"#
#"are vertical asymptotes"#
#"solve "3x^2+2x-1=0rArr(3x-1)(x+1)=0#
#rArrx=-1" and "x=1/3" are the asymptotes"#
#"horizontal asymptotes occur as"#
#lim_(xto+-oo),f(x)toc "( a constant)"#
#"divide terms on numerator/denominator by the "#
#"highest power of x that is "x^2#
#f(x)=((12x)/x^2+52/x^2)/((3x^2)/x^2+(2x)/x^2-1/x^2)=(12/x+52/x^2)/(3+2/x-1/x^2)#
#"as "xto+-oo,f(x)to(0+0)/(3+0-0)#
#rArry=0" is the asymptote"#
