To find the vertical, horizontal, or slant asymptotes for ( f(x) = \frac{3x^2 + 4}{x+1} ):

Vertical Asymptotes: Set the denominator equal to zero and solve for ( x ). Vertical asymptotes occur where the function is undefined.
( x + 1 = 0 )
( x = 1 )Therefore, the vertical asymptote is ( x = 1 ).

Horizontal Asymptotes: Compare the degrees of the numerator and denominator. If the degree of the numerator is less than the degree of the denominator, there is a horizontal asymptote at ( y = 0 ). If the degrees are equal, divide the leading coefficients to find the horizontal asymptote. If the degree of the numerator is greater, there is no horizontal asymptote.
In this case, the degree of the numerator (2) is less than the degree of the denominator (1). So, there is a horizontal asymptote at ( y = 0 ).

Slant Asymptotes (Oblique Asymptotes): If the degree of the numerator is exactly one more than the degree of the denominator, there may be a slant asymptote. To find it, perform polynomial long division or synthetic division.
( \frac{3x^2 + 4}{x+1} = 3x + 2  \frac{2}{x+1} )
The slant asymptote is the equation of the linear term, which is ( y = 3x + 2 ).

When evaluating a onesided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
