identify the domain and range of the function graphed below

Answer:
Part 1) The domain is
[tex]x\leq 4[/tex]
All real numbers less than or equal to 4
Part 2) The range is
[tex]y\geq 0[/tex]
All real numbers greater than or equal to 0
Step-by-step explanation:
Part 1) Find the domain
Observing the graph
we know that
The domain is the interval for x ------> (-∞,4]
so
[tex]x\leq 4[/tex]
All real numbers less than or equal to 4
Part 2) Find the range
Observing the graph
we know that
The range is the interval for y ------> [0,∞)
[tex]y\geq 0[/tex]
All real numbers greater than or equal to 0
