OpenStudy (rational):
look only at "y" values column
whats the minimum value you see ?

5
OpenStudy (rational):
Yes! so "5" is the minimum value of h(x)
OpenStudy (rational):
lets find the minimum value of g(x)
OpenStudy (rational):
|dw:1432430618074:dw|
OpenStudy (rational):
look at the graph
that blue point is the one having minimum value, right ?

right
OpenStudy (rational):
whats the "y" value of that point ?
OpenStudy (anonymous):
-4
OpenStudy (rational):
you're good!
so the minimum value of g(x) is -4
OpenStudy (anonymous):
ok what about f(x)?

Would it be -4 for f(x)?
OpenStudy (rational):
minimum value would be -4+2 = -2 for f(x)
OpenStudy (rational):
f(x) : -2
g(x) : -4
h(x) : 5
who has the smallest value ?
OpenStudy (anonymous):
f(x)?
OpenStudy (rational):
careful with negative numbers
