Transcript text: The entire graph of the function $h$ is shown in the figure below. Write the domain and range of $h$ using interval notation.
(a) domain = $\square$
(b) range $=$ $\square$
Solution
Solution Steps
Step 1: Find the domain
The domain represents the set of all possible x-values. The graph starts at $x=-5$ with a closed circle and ends at $x=4$ with an open circle. So the domain is $[-5, 4)$.
Step 2: Find the range
The range represents the set of all possible y-values. The maximum y-value is $3$ included and the minimum y-value is $-4$ not included. So the range is $(-4,3]$.
