Functions
VI.a., II.a.
Domain of functions:
Functions work like domains of rationals.
Two possibilities:
I: no zeroes in the denominator
2: radicands must be greater than or equal to 0
Example: Find the domain of the function

Quadratic Equations and Solving
II.e.
Completing the Square:
Another method of solving unfactorable equations:
Given ax2 + bx + c = 0
1) let a = 1 (if not already)
2) isolate variables and constants on opposite sides
2
b
3) add to both sides
2
4) factor
Quadratic Equations and Solving
II.e.
Quadratic equation:
ax2 + bx + c = 0
where a,b, and c are real numbers
Zero Product Property:
If AB = 0, then either A = 0 or B = 0
Solve by factoring:
1. get all terms on one side
2. factor completely
3. apply zero p
