Question

The horizontal asymptote of the rational function f(x)= −2/+2 (x minus 2 over x plus 2) is *

Answer 1

9514 1404 393

Answer:

y = 1

Explanation:

The horizontal asymptote can be found as the ratio of the highest-degree terms in the numerator and denominator.

f(x) = (x -2)/(x +2)

lim (x→ ±∞) of f(x) = x/x = 1
