Answer:
Increasing in x < 7 and decreasing in x > 7.
Step-by-step explanation:
g(x) = 1 - ![(x-7)^{2}](https://tex.z-dn.net/?f=%28x-7%29%5E%7B2%7D)
![\frac{dg(x)}{dx} = -2(x - 7)](https://tex.z-dn.net/?f=%5Cfrac%7Bdg%28x%29%7D%7Bdx%7D%20%3D%20-2%28x%20-%207%29)
<u>If a function is increasing in a interval, its first derivative is positive and if a function is decreasing in an intreval, its first derivative is negative.</u>
Using this concept here,
Substitute x > 7,
the first derivative is negative.Hence it is decreasing in this interval.
Substitute x < 7,
The first derivative is positive.Hence it is increasing in this interval.
Hence the answer is increasing in x < 7 and decreasing in x > 7.
Answer:
If the price is p and the cost is c, then
