Evaluating Functions for Inputs in a Given Domain

GIven the function machine, find the output if x = -2.

• f(x)=9

• f(x)=-15

• f(x)=-9

• f(x)=21

Given f(x) = -2x+13

Find f (10)

• -7

• 1

• -8

• 7

Given f(x) = x² Find f(-8)

• 64

• -64

• -16

• 16

What is the proper word for all of the x values or inputs?

• Domain

• Range

• Relation

• Function

GIven the function machine, find the output.

• -2

• 24

• 10

• 2

GIven the function machine, find the output.

• 35

• 15

• 8

• 53

Given the graph of the function

Find f(2)

• -4

• 8

• 0

• 5

What is the proper word for all of the y values or outputs?

• Domain

• Range

• Relation

• Function

Determine if the relation is a function and explain your answer.

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

• Yes, because each x-value has only one y-value paired with it.

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

• No, because each x-value has only one y-value paired with it.

Determine if the relation in the table is a function or is not a function.

• Yes, it is a function.

• No, it is not a function.
