y = 50x
What is the value of y when x = 0?

• y = 0

• y = 50

• y = 100

• y = 1

y = 7x + 49
What is the value of y when x = -12?

• y = -12

• y = -35

• y = -42

• y = -49

Evaluate the function rule: 
y = x - 1           for         x = -2 

• y = 3 

• y = -3 

• y = 4 

• y = -4 

Evaluate the function: 
y = 3x + 2      for   x = 5 

• y = 18 

• y = 17 

• y = 56 

Output values are known as...

• domain

• range

• function

• relation
