Answer:
Step-by-step explanation:
A relation is said to be a function when each input value (x-value) show a distinct output value (y-value).
From the table attached,
For input value x = 0, there are multiple values of output values (y = -2, -1, 0, 1, -2).
Therefore, data given in the table doesn't represent a function.
 
        
             
        
        
        
F(x) = x + 2
when x = 1, f(1) = 1 + 2 = 3
Therefore range for x ≠ 1 is y ≠ 3.
        
             
        
        
        
Answer:
To see if a table of values represents a linear function, check to see if there's a constant rate of change. If there is, you're looking at a linear function!
