Question

Anyone know the domain and range please halp T.T

Answer 1

• Domain: x ∈ [- 1, 5)
• Range: y ∈ [- 3, 3)

Explanation:

Look at the graph to identify its domain and range.

Domain, the set of x-values, is between - 1 on the left and 5 on the right.

The - 1 is included as closed circle and the 5 is not included as open circle.

So the domain is:

• x ∈ [- 1, 5)

The range, the set of y-values, is between - 3 on the bottom and 3 on the top.

The - 3 is included as point on the graph, the 3 is excluded as represented by an open circle.

So the range is:

• y ∈ [ - 3, 3)
