Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.
First, differentiate f(x)
Next, find the zeros of f'(x) by factoring.
Now, we substitute these x-values into the original equation to find the coordinates.
(-2.667, 11.481), (0, 2)

Answer:
205 ft
Step-by-step explanation:
Let w represent the width of the rectangle. Then the length is (6w-17) and the area is ...
A = LW
7585 = (6w-17)(w)
6w² -17w -7585 = 0
Perhaps most straightforward is using the quadratic formula to solve this.
For ax² +bx +c = 0, the solution is x = (-b±√(b²-4ac))/(2a). For the above quadratic, the solution is ...
The width is 37 feet, so the length is ...
6(37) -17 = 205 . . . feet
The length of the rectangle is 205 feet.
