Chapter 3.2: Reciprocal of a Quadratic Function
a) f(x) = 3/(x^2 - 4)
a) f(x) = 3/(x^2 - 4)
- Domain : 3/(x+2)(x-2)
{XɛR, x ≠-2 , x ≠ 2}
x→ -2 , y→-∞
x→ 2ˉ , y → -∞
- Range : y>0 or y< -0.75
- Asymptotes:
x→ 2ˉ , y → -∞
Horizontal asymptote : x→ - ∞ , y → 0
x→ ∞ , y→0
Therefore, y = 0.
Therefore, y = 0.
- x- intercept : -2 and 2
- y-intercept : 0
