Answer:
If you end up with the exact opposite of what you started with (that is, if f (–x) = –f (x), so all of the signs are switched), then the function is odd.
Step-by-step explanation:
We will proceed to resolve each case to determine the solution.
we know that
m of pipe weighs
kg
so
by proportion
<u>Find the weighs of each case</u>
<u>case A)</u>
m of pipe weighs
kg


therefore
The statement case A) is False
<u>case B)</u>
m of pipe weighs
kg


therefore
The statement case B) is False
<u>case C)</u>
m of pipe weighs
kg


therefore
The statement case C) is True
<u>case D)</u>
m of pipe weighs
kg


therefore
The statement case D) is False
therefore
<u>the answer is</u>
m of pipe weighs
kg
