Question

Which set

represents the
domain of the
function shown?
{(-3, 6), (0, 2), (4,
7), (11, 15)}
Select one:
a. {(6,-3), (2,0), (7,4),
(15, 11)
b. {2, 6, 7, 15)
c. {-3, 0, 4, 11)
d. (-3,0, 2, 4, 6, 7, 11,
15)

Answer 1

The correct answer is: c. {-3, 0, 4, 11}

Explanation:

A function consists of ordered pairs. In the ordered pairs, the first element is the input and second value is the output.

All the possible set of inputs for a function are called domain.

Given function is:

{(-3, 6), (0, 2), (4, 7), (11, 15)}

The domain set will consist of the first elements of all the ordered pairs.

The domain of this function is: {-3,0,4,11}

Hence,

The correct answer is: c. {-3, 0, 4, 11}
