Transcript text: The entire graph of the function $f$ is shown in the figure below. Write the domain and range of $f$ using interval notation.
(a) domain = $\square$
(b) range $=$ $\square$
Solution
Solution Steps
Step 1: Find the Domain
The domain of a function is the set of all possible x-values. The graph starts at $x=-3$ with a closed circle and ends at $x=2$ with an open circle. So, the domain includes -3 and goes up to, but does not include, 2.
Step 2: Write the domain in interval notation
The domain in interval notation is $[-3, 2)$.
Step 3: Find the Range
The range of a function is the set of all possible y-values. The lowest y-value on the graph is -4 with a closed circle and the highest is 5 with a closed circle.
