y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
 
        
             
        
        
        
Answer:
x = - 3
Step-by-step explanation:
note that y = f(x)
locate y = 3 on the y- axis, go horizontally across to meet f(x) at (- 3, 3 ) , then
x = - 3 when f(x) = 3
 
        
             
        
        
        
Answer:
