Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. o {5} {1, 2, 3, 5, 7, 8, 11, 14}

Step-by-step explanation:

Option 2 -  

Step-by-step explanation:

Given : A = {2, 5, 8, 11, 14} and B = {1, 3, 5, 7}.

To find : ?

Solution :

The intersection of two sets A and B is the set containing all elements of A that also belong to B and nothing else.

A = {2, 5, 8, 11, 14}

B = {1, 3, 5, 7}

The common elements are 5.

So,

Therefore, Option 2 is correct.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
