Given g(x)=
[6x for 0 < x < or = 2
[3x+3 for 2 < x < or = 8
[5x4 for 8 < x < or = 12
Determine g(6)
Briefly explain

Algebra 
Reiny,
They should have also asked you to graph f(x), that would explain everything very nicely.
at g(6) the value of x falls in the domain
2 < x ≤ 8
so g(x) = 3x+3 for those values of x
then
f(6) = 3(6) + 3 = 21 
Algebra 
Reiny,
whenever I typed f(x) above, it should have said g(x).

Algebra 
Alicia,
Thanks again!
