How do you find vertical, horizontal and oblique asymptotes for (2x+sqrt(4-x^2)) / (3x^2-x-2)?

Horizontal: uarr x = 1 and x=-2/3 darr. Graph is inserted. Look at the ends x = +-2.

Explanation:

To make y real, -2<=x<=2.

The equation is y=(2x+sqrt(4-x^2))/((3x+2)(x-1))

So, x-1=0 and 3x+2=0 give vertical asymptotes.

As x is bounded, there is no horizontal asymptote, and for the same

reason, there is no slant asymptote.

The illustrative graph is inserted.

graph{y(x-1)(3x+2)-2x-sqrt(4-x^2)=0 [-10, 10, -5, 5]}
