1.Easy
xyx = 3

Find the limit L = limx→3 (x2 − 2x − 3)/(x − 3).

f(x) = (x2 − 2x − 3)/(x − 3)x → 3
L =
2.Easy
xyx = −2

Find the limit L = limx→−2 (x2 − x − 6)/(x + 2).

f(x) = (x2 − x − 6)/(x + 2)x → −2
L =
3.Medium
xyy = L

Find the limit L = limx→∞ (√(x2 − 8x) − x).

f(x) = √(x2 − 8x) − xx → ∞
L =
4.Medium
xyy = L

Find the limit L = limx→∞ (√(x2 − 4x) − x).

f(x) = √(x2 − 4x) − xx → ∞
L =
5.Hard
xyx = 0

Find the limit L = limx→0 (e3x − 1 − 3x)/x².

f(x) = (e3x − 1 − 3x)/x²x → 0
L =
6.Hard
xyx = 0

Find the limit L = limx→0 (1 − cos 5x)/(x²), with x in radians.

f(x) = (1 − cos 5x)/(x²)x → 0
L =
