The domain of a function is the set of all possible independent values that a function can have. It is the collection of all possible entries.

The range of a function is the set of all possible dependent values that the function can take. It is the collection of all possible outputs.

1.

{(10,9),(-2,-16),(-6,7),(5,8),(8,-16),(-11,9)}​

Domain:

it will be the values ​ highlighted:

{(10,9),(-2,-16),(-6,7),(5,8),(8,-16),(-11,9)}​

D: {10, -2, -6, 5, 8, -11}

Range:

it will be the values ​ highlighted:

{(10,9),(-2,-16),(-6,7),(5,8),(8,-16),(-11,9)}​

R: {9,-16,7,8,-16,9}

2.

Domain:

Here will be all the values of x (the independent variable) in other words all the values of the first column:

D: {4, 1, 4, 16, 10, -19}

Range:

Here will be all the values of y (the dependent variable) in other words all the values of the second column:

R: {-20, -17, -14, 5, 0, -16}

3.

Domain:

here will be all the values of the input set, that is, the set on the left:

D: {-19, -14, -11, -9, 2, 4}

Range:

here will be all the values of the output set, that is, the set on the right:

R: {-16, -13, -11, -9, 9, 10}
