Functions Rule Input

What is the function of the table?

• y=x*6

• y=x+10

• y=x-10

• y=x÷6

Which equation matches the table?

• y = x + 5

• y = 5x

• y = x - 5

• x = y - 5

If my function rule is 4x, what is the OUTPUT if the input is 5?

• 45

• 54

• 9

• 20

If my function rule is x÷3, what is the OUTPUT if the input is 12?

• 9

• 4

• 3

• 36

y=x*7
What is the missing number?

• 5

• 4

• 8

• 7

What is the function of the table?

• y=x+3

• y=x*3

• y=x÷3

• y=x-3

Is this a function? 

• Yes, because every input has exactly one output

• No, because -1 has more than one output 

• No, because 3 is in the input and the output 

What is a rule that assigns exactly one output to ever input? 

• mapping diagram

• table 

• function

• function notation 

Is this a function? 

• Yes, because 15 is assigned the output value of 7 and 9

• No, because 15 has more than one output 

• No, because -1, 0, and 15 have the same output value of 9 

Is the table on the left a function? 

• Yes, because every input has exactly one output

• No, because 1 and 3 have the same output value
