Question

Which set represents the domain of the function shown? {(−3, 6), (0, 2), (4, 7), (11, 15)}

{(6, −3), (2, 0), (7, 4), (15, 11)}

{2, 6, 7, 15}

{−3, 0, 4, 11}

{−3, 0, 2, 4, 6, 7, 11, 15}

Answer 1

The answer would be all the X coordinates from smallest to largest. Your answer is C, -3,0,4,11

Answer 2

Answer: The correct option is (C) {−3, 0, 4, 11}.

Step-by-step explanation: We are to select the set that represents the domain of the function below:

{(−3, 6), (0, 2), (4, 7), (11, 15)}.

We know that

if a function is represented by a set of ordered pairs, then

the set of the first co-ordinate of the ordered pairs will form the DOMAIN of the function

and

the set of the second co-ordinates will form the RANGE of the function.

In the given function, the first co-ordinates of the ordered pairs are -3, 0, 4 and 11.

Therefore, the domain of the given function is given by

{-3, 0, 4, 11}.

Thus, (C) is the correct option.
