Answer:
width of a singles court = 27 feet
Step-by-step explanation:
Width of a doubles tennis court = 36 feet
Width of a singles tennis court = 75% of 36
Suprisingly the answer is $280,000. This is answer because when you round 35.50 it is 40. When you round 6,789 it is 7,000. 40 times 7,000 is 280,000

the derivitive is just the slope
minimum happens when the derivitive goes from negative to positive, imagine a slope of the function, the minimum is where the slope goes from neative to positive, and to get there, it has to pass through 0
max happens when the derivitive goes from positive to negative
increaseing is when the derivitive is positive
so, based on what you said, the slope of f(x) is 0 at x=-3, x=1 and x=2 since those are where the derivitive is 0 (derivitive is just the slope)
A and B are wrong because the derivitive isn't 0 at those points
C is correct because increasing means that the derivitive is positive, and so therefo since the only hoirontal place in between 1 and 2 is 1.5, it must remain positive throughout and not dip down, C is right
D is wrong then
answer is C
