1.Easy
xyx = 5

Find the limit L = limx→5 (x2 − 4x − 5)/(x − 5).

f(x) = (x2 − 4x − 5)/(x − 5)x → 5
L =
2.Easy
xyx = −4

Find the limit L = limx→−4 (x2 − 16)/(x + 4).

f(x) = (x2 − 16)/(x + 4)x → −4
L =
3.Medium
xyy = L

Find the limit L = limx→∞ (1 + 1/x)3x. Give a decimal value.

f(x) = (1 + 1/x)3xx → ∞
L =
4.Medium
xyy = L

Find the limit L = limx→∞ (1 − 2/x)x. Give a decimal value.

f(x) = (1 − 2/x)xx → ∞
L =
5.Hard
xyx = 0

Find the limit L = limx→0 (e1.5x − 1 − 1.5x)/x².

f(x) = (e1.5x − 1 − 1.5x)/x²x → 0
L =
6.Hard
xyx = 0

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

f(x) = (ex − 1 − x)/x²x → 0
L =
