Finding Domain and Range from Graphs Practice

1. What is the domain of ‍$h$?

   
   

   Choose 1 answer:

   1. $-5 \leq x \leq 7$
   2. The $x$-values ‍$-5$, $-2$, $6$ and $7$
   3. $-2 \leq x \leq 6$

   4. The $x$-values ‍$-2$, $-1$, $1$, $5$ and $6$

2. What is the domain of ‍$f$?

   
   

   Choose 1 answer:

   1. $-9 \leq f(x) \leq 9$
   2. $-8 \leq f(x) \leq -4$
   3. $-9 \leq f(x) \leq -2$

   4. $-2 \leq f(x) \leq 9$

3. What is the domain of ‍$g$?

   
   

   Choose 1 answer:

   1. $-7 \leq x \leq 4$
   2. $-4 \leq x \leq 8$
   3. The $x$-values ‍$-4$, $-3$, $0$, $2$ and $8$

   4. The $x$-values ‍$-7$, $-4$, $0$, $3$ and $4$

4. What is the domain of ‍$h$?

   
   

   Choose 1 answer:

   1. $-4 \leq h(x) \leq 6$
   2. The $h$-values ‍$-5$, $-4$, $0$, $2$ and $4$
   3. The $x$-values ‍$-4$, $-2$, $2$, $4$ and $6$
   4. $-5 \leq h(x) \leq 4$
