Representing, Naming, & Evaluating Functions

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

• mapping diagram
• table 
• function
• function notation 

What is the dependent variable of a function? 

• the input 
• the output 
• the function notation 

What is the independent variable of a  function? 

• the input 
• the output 
• the function notation 

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

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 

What is the result after applying the function machine rule? 

• the input
• the output 
• the function notation 
• a linear equation 

Evaluate the function rule: 
 y = 5 x - 2    for x = 3 

• y = 13 
• y = 12 
• y = 11.5 
• y = 17 

Evaluate the function rule: 
y = 6(x - 6)  for x = 7 

• y = 36 
• y = 6 
• y = 1 
• y = 7 

• 8
