Question

State the domain and range of the following function.

{(2,3), (7.9), (4,-7), (6,2), (3,-5)}
A. Domain: (-7, -5, 2, 3, 7); Range: (2, 4, 6, 9)
B.Domain: {2, 2, 3, 4, 7); Range: {-7,-5, 2, 9,3}
C.Domain: {2, 3, 4, 6, 7); Range: {-7, -5,2. 3,9}
D.Domain: {-7, -5, 2, 3, 9); Range: {2, 3, 4, 6, 7}

Answer 1

The domain of the function is {2, 3, 4, 6, 7} and the range is {-7, -5, 2, 3, 9}, which corresponds to the unique x-values and y-values from the set of ordered pairs of the function.

Step-by-step explanation:

The domain of a function is the set of all possible input values (x-values), and the range is the set of all possible output values (y-values). In this case, for the given function {(2,3), (4,-7), (6,2), (7,9), (3,-5)}, the domain is the set of the first coordinates from each ordered pair and the range is the set of the second coordinates.

So, the correct domain for this function is {2, 3, 4, 6, 7}, which are the unique x-values from the ordered pairs. The correct range of this function is {-7, -5, 2, 3, 9}, which are the corresponding unique y-values from the ordered pairs.

Therefore, the correct answer is: Domain: {2, 3, 4, 6, 7} and Range: {-7, -5, 2, 3, 9}.
