1. 2.1-2.2 Relations, Functions, and Linear Equations
Algebra II CP

2. Vocabulary Domain Range Discrete vs. Continuous Function
Linear Equation
Standard Form

3. Ex 17: Find the Domain and Range then determine whether each relation is a function.
{(3, 2), (2, -4), (3, 5), (0, -7)}
y=x+3

4. Ex :
State the domain and range of each relation below then determine if it is a function.
Vertical Line Test

5. Function Notation
y=2x+3
y=|-x+5|

6. Ex :
Given f(x) = 2x³ + x - 4 find each value:
f(-2)
f(3x)

7. Ex :
Write each equation in Standard Form then identify the A, B, and C
y = 4x +3
2x = .75y +6

8. Ex last one: Find the x- and y-intercept and then graph the equation.
y = -2x + 5
2x + 3y = -6
