What are the asymptotes of y=(2x^2 +1)/( 3x -2x^2)?

1 Answer

Vertical Asymptotes:
x= 0^^x=-3/2

Horizontal Asymptote:

y=-1

Explanation:

y=(2x^2+1)/(3x-2x^2)=-(2x^2+1)/(2x^2+3x)=-(2x^2+1)/(x(2x+3))

  1. Verical Asymptotes
    Since denominator could not be 0
    we find the possible values of x that would make the equation in the denominator 0

x(2x+3)=0

Therefore

x=0

(2x+3)=0=>x=-3/2

are vertical asymptotes.

  1. Horizontal asymptotes

Since the degree of numerator and denominator is the same, we have an horizontal asymptotes

y~~-(2x^2)/(2x^2)=-1

:.y=-1 is a horizontal asymptotes for xrarr+-oo

graph{-(2x^2+1)/(x(2x+3)) [-25.66, 25.65, -12.83, 12.82]}
