what are the domain and the range of the function? domain: range:
Answer
Explanation:
Step1: Identify domain from graph
The graph has endpoints at (x=-2) (open - circle) and (x = 4) (closed - circle). The domain is the set of all (x) - values. So, the domain is (-2\lt x\leqslant4). In interval notation, it is ((-2,4]).
Step2: Identify range from graph
The graph has endpoints at (y = 7) (open - circle) and (y=-5) (closed - circle). The range is the set of all (y) - values. So, the range is (-5\leqslant y\lt7). In interval notation, it is ([-5,7)).
Answer:
Domain: ((-2,4]), Range: ([-5,7))
