Solving Systems by Graphing

What is the definition of function?

• Has inputs and outputs
• Every input has only ONE output
• Inputs have different outputs every time
• x-values and y-values

All of the y values or outputs are called what?

• Domain
• Range
• Relation
• Function

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Function

Is this table a function or not a function? 

• Function
• Not a Function

What is the range?

• x≥0

• y≥0

• All real numbers

• {0, 1, 2, 3, 4,...}

What is the domain of the function?

• x>3 
• x≥-3
• y≤4
• y<4

Identify the domain of the following relation:

• {-6, 14, 2, 28}
• {(-6,14), (0,32), (2,38), (4,44)}
• {-6, 0, 2, 4}
• {14, 32, 38, 44}

What is the RANGE?

• -4 ≤ x ≤ 1

• -4 ≤ y ≤ 1

• -2 ≤ x ≤ 3

• -2 ≤ y ≤ 3

Identify the slope. (m = rise / run)

What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)
