Unit 2 Lesson 4 Practice

All of the x values or inputs are called what?

• Domain
• Range
• Relation
• Dependent variable

Which graph does NOT pass the vertical line test? A vertical line should only touch one point at a time, if it is a function.

• Graph 1
• Graph 2
• Graph 3
• Graph 4

Is the relation a function? Why.

• Yes, because the x-value 11 has two y-values pair 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 pair with it.
• No, because each x-value has only one y-value paired with it.

Define this graph. Does it pass the vertical line test?

Identify the range of the following relation:

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