Finding Domain and Range from Graphs Practice

The domain of a function is the set of all inputs for which the function is defined.

According to the graph, ‍$h$ is defined for certain points only. So the domain is the list of the input ‍$x$-values where ‍$h$ is defined (or where there are points on the graph). This means the domain of ‍$h$ is the ‍$x$-values ‍$-2$, $-1$, $1$, $5$ and $6$.

In conclusion, the domain of the function is the $x$-values ‍$-2$, $-1$, $1$, $5$ and $6$.

The range of a function is the set of all the possible function outputs.

According to the graph, the largest number that is an output of $f$ is ‍-2, and the smallest number is ‍-9. Every number between them is also an output of ‍$f$ for some input. Therefore, the range of ‍$f$ is $-9 \leq f(x) \leq -2$.

In conclusion, the range of the function is $-9 \leq f(x) \leq -2$.

The domain of a function is the set of all inputs for which the function is defined.

According to the graph, ‍$h$ is defined for certain points only. So the domain is the list of the input ‍$x$-values where ‍$h$ is defined (or where there are points on the graph). This means the domain of ‍$h$ is the ‍$x$-values ‍$-2$, $-1$, $1$, $5$ and $6$.

In conclusion, the domain of the function is the $-7 \leq x \leq 4$.

The range of a function is the set of all the possible function outputs.

According to the graph, ‍$h$ is defined for certain points only. So the range is the list of the output $h(x)$-values where ‍$h$ is defined (or where there are points on the graph). This means the domain of ‍$h$ is the ‍$h(x)$-values ‍$-4$, $-2$, $2$, $4$ and $6$.

In conclusion, the range of the function is $h(x)$-values ‍$-4$, $-2$, $2$, $4$ and $6$.
