What are the domain and range of the function below?

Answer:
Domain ={0,infinity)
Range = (-infinity, 4]
Step-by-step explanation:
Given a graph with curve which has y intercept 4.
It passes x axis at 4 and extends fully
The domain is the set of values x can take
In the graph horizontal axis is x axis.
Hence from the graph we see that x can take values from 4 including 4 upto infinity.
Hence domain is x>=4
For range, we consider the values of y as per graph.
WE find that y is not taking values >4
Hence Range = (-infty, 4]
Answer:
[tex]Domain=[0,\infty)[/tex]
[tex]Range=(-\infty,4][/tex]
Step-by-step explanation:
We need to find the domain and range of the function.
Domain : It is the set of input values or x values. In a graph, domain of the function represented by the x-axis.
Range : It is the set of output values or y values. In a graph, range of the function represented by the y-axis.
From the given graph it is clear that it is defined for [tex]0\le x<\infty[/tex] and [tex]-\infty <y\le 4[/tex].
We have closed circle at (0,4). It means, 0 is included in the domain and 4 is included in the range.
[tex]Domain=[0,\infty)[/tex]
[tex]Range=(-\infty,4][/tex]
Therefore, [tex]Domain=[0,\infty)[/tex] and [tex]Range=(-\infty,4][/tex].
