The limit of (x2 - 1) / (x - 1) as x tends to 1 is:
The limit of sin x / x as x tends to 0 is:
The limit of (3x + 2) as x tends to 2 is:
A function f is continuous at x = a if the limit as x tends to a equals:
The limit of (1 + 1/n)^n as n tends to infinity is:
1. B, 2. A, 3. D, 4. B, 5. D
(x + 1)(x - 1) / (x - 1) = x + 1, which tends to 2.
This is a standard limit equal to 1.
Substitute x = 2: 6 + 2 = 8.
Continuity needs the limit to equal the function's value.
This is the definition of the number e.
