Open Ended

What is the domain and the range for number 2? Is it a function?

Open Ended

What is the domain and the range for number 4? Is it a function?

The following questions...

are not in your notebook. This is going to be the extra practice for today. There will only be ONE assignment for today!

Multiple Choice

Is this a function?  Why or why not?

• No, the domain numbers are repeated.
• No, it passes the Vertical Line Test.
• Yes, it passes the Vertical Line Test.
• Yes, the range numbers are not repeated.

Multiple Choice

Is this a function?  Why or why not? 

• Yes, because none of the domain numbers repeated.
• Yes, because none of the range letters repeated.
• No, because 3 goes to A and 4 goes to A.
• No, because A gets used twice.

Multiple Choice

Does this table represent a function?

• Yes!

• No!

• I Don't Know

Open Ended

Why is the following relation NOT a function?

(2, 3), (4, 9), (3, 8), (4, 15)

Multiple Choice

Which set of ordered pairs is not a function?

• (1, 3), (2, 7), (3, 8), (4, 11)

• (2, 3), (4, 9), (3, 8), (4, 15)

• (1, 2), (3, 5), (6, 9), (7, 11)

• (-9, 4), (-6, 3), (-2, 8), (0, 21)

Multiple Choice

Give the range of the set of ordered pairs: (2, 11), (9, -3), (7, 21), (-8, 6)

• $\left\{-8,\ 2,\ 7.9\right\}$

• $\left\{-3,\ 6,\ 11,\ 21\right\}$

• $-8<x<9$

• $-3<y<21$

The next questions...

These are not in your notebook, but this quizizz will count as your notes and your practice for today. So these are extra questions I've added in about one-to-one and onto.

Multiple Choice

Which of the following relations is a one-to-one function?

• {(0,2), (0,4), (0,5), (0,6)}

• {(5,-1), (6,3), (1,2), (7,-8)}

• {(1,2), (3,4), (-1,-2), (1,5)}
