• Relation

• Linear

• Exponential

• Function

What is the test to determine if a graph represents a function?

Look at the graph. Is the relation a function?

• yes

• no

Is this mapping a function or not a function? 

• Function
• Not a Function 

If f(x) = 2x + 1, find f(1).

• f(1) = 1

• f(1) = 4

• f(1) = 0

• f(1) = 3

How would you write y = 2x - 3 in function notation?

• y = 2x-3

• f = 2x - 3

• f(x) = 2x-3

Solve for x: 7 (2x - 4) = 42

• x = 2

• x = 8

• x= 5

• x = 9
