Answer:
A value between 3 and 5 (exclusive of both) will do.
Example: You could choose 4 as a possible value.
Step-by-step explanation:
[tex]f(9)=9[/tex] means you have the ordered pair (9,9) on your graph.
[tex]f(10)=10[/tex] means you have the ordered pair (10,10) on your graph.
[tex]f(7)=5[/tex] means you have the ordered pair (7,5) on your graph.
[tex]f(3)=-4[/tex] means you have the ordered pair (3,-4) on your graph.
[tex]f(5)=3[/tex] means you have the ordered pair (5,3) on your graph.
[tex]f(4)=-1[/tex] means you have the ordered pair (4,-1) on your graph.
Since f is increasing f(6) can be any value between 3 and 5, exclusive.
So you can assign any value for [tex]f(6)[/tex] such that [tex]3<f(6)<5[/tex]. We cannot conclude with out further information what value between 3 and 5, exclusive.
