Question

The graph of the relation S is shown below. Give the domain and range of S.

Write your answers using set notation.

Answer 1

The coordinates of the plotted points

• (-1,3)
• (1,-1)
• (4,0)
• (4,1)

Domain:-

Set of x values

• {-1,1,4}

Range

Set of y values

• {3,-1,0,1}

Answer 2

Explanation:

The graph has coordinates:

• (-1, 3), (1, - 1), (4, 0), (4, 1)

The domain of S:

• x(S) = {- 1, 1, 4}

The range of S:

• y(S) = [-1, 0, 1, 3}
