Question

Determine the domain and range of the function shown below. Assume the entire function is shown. Domain: Range:

Answer 1

The function is made of the following ordered pairs:

(-1,-3) (1, -5) (2, 3) (3, 6) (5, 6) (7, -1)

The first coordinate of the ordered pairs is the input value and the second coordinate is the output value of the function.

The domain is the set of all the input values as shown below:

Domain: {-1, 1, 2, 3, 5, 7}

Range: {-3, -5, 3, 6, -1}

Sorting the values of the range.

Range: {-5, -3, -1, 3, 6}
