To find the asymptotes of the function (y = \frac{3x^2 + 2x - 1}{x^2 - 4}), we need to look at both the vertical and horizontal asymptotes.

**Vertical Asymptotes:** Vertical asymptotes occur where the denominator of a rational function is equal to zero, but the numerator is not zero. In this case, the denominator (x^2 - 4) is equal to zero when (x = 2) or (x = -2). However, at these points, the numerator (3x^2 + 2x - 1) is not equal to zero. Therefore, the vertical asymptotes are (x = 2) and (x = -2).

**Horizontal Asymptotes:** Horizontal asymptotes occur when the degree of the numerator is less than or equal to the degree of the denominator. In this case, the degree of the numerator is 2 and the degree of the denominator is also 2. To find the horizontal asymptote, divide the leading terms of the numerator and denominator. The horizontal asymptote is the ratio of the leading coefficients. So, the horizontal asymptote is (y = \frac{3}{1}) or simply (y = 3).

Therefore, the function (y = \frac{3x^2 + 2x - 1}{x^2 - 4}) has vertical asymptotes at (x = 2) and (x = -2), and a horizontal asymptote at (y = 3).

When evaluating a one-sided 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.
