4. Limits
Value of limit does not depend on actual value of the function or on whether the function is even defined at that point.
See examples on top of p. 61

5. Properties of Limits
Sum: limit of the sum of 2 functions is the sum of their limits
Difference: limit of the difference of 2 functions is the difference of their limits
Product: limit of the product of 2 functions is the product of their limits
Constant multiple: limit of a constant times a function is the constant times the limit of the function.
Quotient: limit of the quotient of 2 functions is the quotient of their limits provided the limit of the denominator is not zero.
Power: limit of a rational power of a function is the power of the limit of the function provided the limit of the function is a real number.

6. Examples
limx→c(x3 + 4x2 – 3)
limx→c X4 + x2 – 1
X2 + 5
(Ex. 5 and 6)

7. Finding limits by substitution
If the function is a polynomial, then the limit at a point is the value of the function at that point.
i.e. lim x3 + 2x2-5x +3 =
x→2
Works for functions with expressions in denominator as long as denominator does not become zero at that value
(ex. 7-11)
