<h3>Answers:</h3>
- (a) The function is increasing on the interval (0, infinity)
- (b) The function is decreasing on the interval (-infinity, 0)
=======================================================
Explanation:
You should find that the derivative is entirely negative whenever x < 0. This suggests that the function f(x) is decreasing on this interval. So that takes care of part (b).
The interval x < 0 is the same as -infinity < x < 0 which then translates to the interval notation (-infinity, 0)
Similarly, you should find that the derivative is positive when x > 0. So the function is increasing on the interval (0, infinity)
The perimeter of a rectangle is calculated as
Perimeter= 2(length + breadth )
So, Perimeter = 2*length + 2*breadth
Now we are given the length as 34.2 meters and breadth as 27.8 meters
So the perimeter will be
2(34.2+27.8) meters
which equals 2(62) meters
Hence Perimeter = 124 meters
