what is the maximum value of g(x)?

OpenStudy (anonymous):

8

OpenStudy (zzr0ck3r):

what is the max value of f(x)?

OpenStudy (anonymous):

9?

OpenStudy (zzr0ck3r):

what is the min value of f(x)?

OpenStudy (zzr0ck3r):

and yes 9 is correct for the max

OpenStudy (anonymous):

oh ok. i just wanted to make sure 9 was the max. thank you

OpenStudy (zzr0ck3r):
