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

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

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

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

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

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

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

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