The mathematical expression 2 e v means:
2 is an element of set w
2 is a subset of set w
2 is an element of set v
none of the above

Third option us correct.

Step-by-step explanation:

Since we have given that

The mathematical expression i.e.

That mean, 2 belongs to set V.

⇒ 2 is an element of set V.

So, it implies that V is the set of elements in which 2 as an element is present in the set, i.e. 2 ∈ V

Hence, Third option us correct.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
