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"
