Question

Identify intervals on which the function is increasing, decreasing, or constant.

g(x) = 2 - (x - 7)2

OPTIONS:

Increasing: x < 2; decreasing: x > 2

Increasing: x < -7; decreasing: x > -7

Increasing: x < 7; decreasing: x > 7

Increasing: x > 2; decreasing: x < 2

Answer 1

@*Insert Name Here* what about this one?

Answer 2

you need to find the first derivative first

Answer 3

here g'(x) = -2(x-7)

for increasing g'(x) > 0
and for decresing g'(x)<0

Answer 4

hope u can do now..

Answer 5

so is it b?

Answer 6

try
c

Answer 7

So it is C? thank yoU!

Answer 8

yw
but do you know how it s coming

Answer 9

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...
