If f(x)=3x-9, find f(5).

• f(5) = 6

• f(5) = 16

• f(5) = -4

• f(5) = 24

If f(x)=2x+25, find f(5).

• f(5) = 60

• f(5) = 40

• f(5) = -15

• f(5) = 35

All of the x values or inputs are called what?

• Domain

• Range

• Relation

• Function

All of the y values or outputs are called what?

• Domain

• Range

• Relation

• Function

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

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair with it.

• No, because the x-value 11 has two y-values pair with it.
