the graph of the piece - wise function f(x) is shown. what is the domain of f(x)? {x|1≤x<5} {x|1≤x≤5} {y|-4≤y<1} {y|-4≤y≤1}
Answer
Explanation:
Step1: Recall domain definition
The domain of a function is the set of all possible x - values.
Step2: Analyze the graph
The graph starts at x = 1 (closed - circle, so x = 1 is included) and ends at x = 5 (open - circle, so x = 5 is not included).
Answer:
{x|1≤x<5}
