Question

Domain and range of this graph

Answer 1

Answer:

  c.  D = {x | x ≥ -3}, R = {y | y ≥ 0}

Step-by-step explanation:

The domain is the horizontal extent of the graph. The range is its vertical extent.

__

We observe that point (-3, 0) is a point on the graph, so x=-3 is included in the domain, and y=0 is included in the range. The only answer choice that has the "or equal to" case included for both x and y is ...

  D = {x | x ≥ -3}, R = {y | y ≥ 0}
