Answer:
The range of the graph is all real numbers greater than or equal to 0.
Step-by-step explanation:
we have

using a graphing tool
The graph in the attached figure
step 1
Find the domain
we know that the radicand of the function must be greater than or equal to zero
so
The domain is the interval ------> [0,∞)

All real numbers greater than or equal to zero
step 2
Find the range
The range is the interval -----> [0,∞)

All real numbers greater than or equal to zero
