Question

Please help me this is due tonight i don’t get it please

Answer 1

Given below.

=================

I can see two graphs and will provide answer accordingly.

First, refreshing our knowledge.

The domain is the set of x-values or input values the function can get and the range is the set of y-values or outputs the function can get.

Graph 5

We see a line with no restrictions, hence:

• Its domain is all real values: x ∈ ( -∞; +∞)
• Its range is all real values: y ∈ ( -∞; +∞)

Graph 8

We see a line with some restrictions.

Its domain is between -1 and 5, the first point is included (it is represented as full circle) and the second one is not included (it is represented as empty circle), so:

• x ∈ [ - 1, 5)

Its range is between - 3 and 3, the first one is included as the graph touches -3 but the second one is not included, so :

• y ∈ [ -3; 3)
