Q13 Determine whether the relation represents a function If

Q13. Determine whether the relation represents a function. If it is a function, state the domain and range.
{(-4, 17), (-3, 10), (0, 1), (3, 10), (5, 26)}
    a. It is a function; domain: {17, 10, 1, 26}; range: {-4, -3, 0, 3, 5}
    b. It is a function; domain: {-4, -3, 0, 3, 5}; range: {17, 10, 1, 26}
    c. It is NOT a function.

Solution

given relation is a function since every output has only one corresponding input.

OR

Since every domain value is paired with one range values, So it\'s a function.

Domain = x-values:

Domain = (-4, -3, 0, 3, 5)

Range = y-values:

Range = (17, 10, 1, 26)

Correct option is B.
