How do you find the asymptotes for y = (3-4x )/( 6x + sqrt(4x^2-3x-5))y=34x6x+4x23x5?

Horizontal: y=-2/3y=23. The graph is real for (-sqrt89+3)/8<=x<=(sqrt89+3)/889+38x89+38.

Explanation:

To make y real, (-sqrt89+3)/8<=x<=(sqrt89+3)/889+38x89+38.

y =(-4+3/x)/(6+sqrt(4-3/x-1/x^2)) to -2/3y=4+3x6+43x1x223, as x to +-oox±.

Look at the dead ends x = (3+-sqrt 89)/8= 1.554 and -0.804x=3±898=1.554and0.804, nearly.
