Question

Identify the set of numbers that makes up the domain in the relation {(-2,-2), (0, 2), (2, 4), (3, -6)}-

0-6,-2, 2,4
0-6-2,0, 2, 3, 4
0-2,0,3, 4
0-2,0, 2, 3​

Answer 1

Option D) (-2, 0, 2, 3)

Explanation:

We are given the following information:

Relation: {(-2,-2), (0, 2), (2, 4), (3, -6)}

We have to find the domain of the given relation.

Any coordinate in a relation (x,y), x becomes a part of the domain and y s the value of function at x and d becomes a part of the range.

So, the domain of the given relation would be collection of all x coordinates of the given tuples.

So the domain of given relation is:

(-2, 0, 2, 3)

Hence, Option D) is the right domain for the given relation.

Answer 2

The correct answer is option no. 4: -2,0, 2, 3​

Explanation:

A domain is the input of the function. If a function is given in the form of ordered pairs, then the first elements of ordered pairs form the domain set.

Given relation is:

{(-2,-2), (0, 2), (2, 4), (3, -6)}-

The set of first elements of each ordered pair is:

{-2,0,2,3}

Hence, option No. 4 is the correct answer ..
