Which Graph Represents Yxover The Domain 2x5 class=

Sagot :

Answer:

4

Step-by-step explanation:

#1 has to be excluded, since it jumps from 4 to 5 and has a hole between x=4 and x=5

#2 loses the extreme values. It would be correct if the domain was [tex]2<x<5[/tex]

#3 is including values in the interval [tex]1<x \leq 2[/tex] which aren't in our domain.

#4 is the remaining one.
