CCSS.8.F.A.3

The mapping shown is:

• Not a function, because there are letters.
• Not a function, because two different numbers go to C.
• A function, because none of the x values go to more than one y value.
• A function, because the numbers are in order.

CCSS.8.F.A.1

The table shown is:

• Proportional because it goes through the origin.
• Linear, because there is a pattern.
• A function, because all of the x values are different.
• All of the above.

CCSS.HSF-LE.A.1B

The table shown is:

• Linear, because it is going up by 2 each time.
• Proportional, because 1 goes evenly into 4 and 2 goes evenly into 6.
• A function, because none of the x values are repeated.
• Not a function because it doesn't start at zero.

CCSS.8.F.A.3

The table shown is:

• Proportional, because it is going up by 2 each time.
• Linear, because it is going up by two each time.
• Not a function, because 1 appears in the table twice.
• A function but non linear, because it doesn't start at zero.
