Answer:
The Median is 20
Arrange the numbers in order
15 20 20 22 25
The middle number is 20
6y=-24x+120
simplified, it's
y=-4+20
The length of each side would be 3 square meters
In the region 0-2, the first derivative has a zero at x=1, and the second derivative (slope of the first derivative line) is positive. This means f(x) will have a minimum at x=1.
Likewise, in the region 4-6, the second derivative is negative and the first derivative is zero at x=5, indicating a maximum there.
These observations narrow the selection to choices A or C. The derivative curve is continuous at x=2 and x=4, so there will not be any discontinuities in f(x)--eliminating selection C.
The best choice is
A.
