@*Insert Name Here*  what about this one?

anonymous · Answer

you need to find the first derivative first

anonymous · Answer

here g'(x) = -2(x-7)

for increasing g'(x) > 0 
and for decresing g'(x)<0

anonymous · Answer

hope u can do now..

anonymous · Answer

so is it b?

anonymous · Answer

try 
c

anonymous · Answer

So it is C? thank yoU!

anonymous · Answer

yw 
but do you know how it s coming

anonymous · Answer

for increasing g'(x) >0 see g'(x)>0 implies -2(x-7) > 0 or 2(x-7) < 0 or x-7 <0 or x<7 and so on...
