vertical asymptote at x = - 3

horizontal asymptote at y = 1

#### Explanation:

Vertical asymptotes occur as the denominator of a rational function tends to zero. To find the equation let the denominator equal zero.

solve : x + 3 = 0 → x = -3 is the equation

Horizontal asymptotes occur as

#lim_(x→±∞) f(x) → 0# If the degree of the numerator and the degree of the denominator are equal , as the are here , both of degree 1 , then the equation can be found by taking the ratio of leading coefficients.

#rArr y = 1/1 = 1 " y = 1 is the equation "# Here is the graph as an illustration.
