Step-by-step explanation:
Around 14 weeks
45*14=630

So around 14 weeks

has critical points where the derivative is 0:

The second derivative is

and
, which indicates a local minimum at
with a value of
.
At the endpoints of [-2, 2], we have
and
, so that
has an absolute minimum of
and an absolute maximum of
on [-2, 2].
So we have



Answer:
(x + 2) (8x + 3)
Step-by-step explanation:
+ 
= (x + 2) (8x + 3)
L = 3/a = 3/8
R = 16/a = 16/8 = 2
