Question
The table above shows some values of x and their corresponding values of y. Which of the following equations shows a possible relationship between x and y?
- y = x + 2
- y = x - 2
- y = 2x + 3
- y = 3x - 2
The correct answer is: y = x + 2
From the table, we observe the value of y is 2, when x is 0. We need to check the options, in what sequence.
Option A :-
y = x + 2
Substitute x = 0, we get
y = 0 + 2
y = 2 (True)
Option B :-
y = x - 2
Substitute x = 0, we get
y = 0 - 2
y = -2 (False)
Option C :-
y = 2x + 3
Substitute x = 0, we get
y = 2(0) + 3 = 0 + 3
y = 3 (False)
Option D :-
y = 3x - 2
Substitute x = 0, we get
y =3(0) -2 = 0 - 2
y= -2 (False)

Use polynomial identities to factor the polynomials or simplify the expressions : 
Polynomial identities are equations that are true for all possible values of the variable. We can perform polynomial multiplication by applying the distributive property to the multiplication of polynomials.
