Question

What is the domain and range ?

Answer 1

Answer:

domain: [0, ∞)

range: (-∞, 0]

Step-by-step explanation:

the domain is all the possible x-values, which is all the numbers from 0 to infinity.

the range is all the possible y-values, which is all the numbers from negative infinity to 0.

Answer 2

The domain refers to the set of possible input values. The domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values shown on the y-axis.

Domain=the set of all x-coordinates={1,2,3,4}.
Range= the set of all y-coordinates={2,3}
