Step-by-step explanation:

Answer 2

Answer:

The domain of the function is { -2 , 0 , 1 , 2 , 3 , 4} ⇒ 1st answer

Step-by-step explanation:

* Lets explain the meaning of the function

- The function is a relation between x and y under condition of

  every x has only one value of y

Ex: The relation {(-1 , 2) , (2 , 4) , (3 , 2)} is a function because

      every x has one value of y

     The relation {(-1 , 2) , (2 , 4) , (2 , 2)} is NOT a function because

      one x has two values of y ⇒ 2 has two values of y  4 and 2

- x is the input and called the domain of the function

- y is the output and called the range of the function

* Lets solve the problem

∵ The set of points = {(-2, -4) , (0 , 0) , (1 , 1) , (2 , 2) , (3 , 1) , (4 , 6)}

- Every x has only one value of y

∴ The set of points is a function

∵ The domain of the function is the values of x

∴ The domain of the function is { -2 , 0 , 1 , 2 , 3 , 4}
