How do you find vertical, horizontal and oblique asymptotes for f(x) = (x)/( 4x^2+7x-2)?

The Vertical Asymptotes are: x=1/4 and x=-2

The Horizontal Asymptote is y=0

There is No Oblique Asymptote.

Explanation:

Finding the vertical asymptote of a rational function is by setting its denominator to zero that is

4x^2+7x-2=0
rArr(4x-1)(x+2)=0

4x-1=0
rArr4x=1
rArrx=1/4

x+2=0
rArrx=-2

The Vertical Asymptotes are: color(red)(x=1/4 and x=-2)

Because the degree of numerator is less than the denominator

So, color(red)(y=0 ) is the Horizontal Asymptote

There is color(red)(No) Oblique Asymptote.
