• 

Is the function linear or nonlinear?

• Linear Function
• Nonlinear Function

Is this function linear or non linear?

• Linear
• Non Linear

Is the relation a linear function?

• No

• Yes

What is the slope of the line?

• 3

• -3

The following is not a function because...

• There are two values that equal 2.

• x = 10 and x = 40 has two values each.

• In the f(x) column, the 5 repeats.

• This table is actually a function.

What is the domain?

• 0, 4, 10, 12

• 1, 2, 4, 5, 10, 12

• 0, 4, 10, 4, 12

• 1, 2, 5

What is the Range?

• {-3, -1, 1, 3, 5, 7, 9}
• {-3, -2, -1, 0, 1, 2, 3}
• -3 ≤ x ≤ 3
• -3 ≤ x ≤ 9
