On a skiing trip, there are five people but only three pairs of skis. How many different groups of three could ski?

3 0

So let's start by naming our people, let's say Robert, Sasha, Tyler, Bryan, and Katie. Now start listing all the ways that they can go in a organized way.
Robert, Sasha, Tyler
Robert, Sasha, Bryan
Robert, Sasha, Katie
Robert, Tyler, Bryan
Robert, Tyler, Katie
Robert, Bryan, Katie
Sasha, Tyler, Bryan
Sasha, Tyler, Katie
Tyler, Bryan, Katie
And that is it, 9, without repeating the same groups

f(-x) = f(x) = 0

Will the opposite of zero always ,sometimes or never be zero

Zero is neutral. Its neither positive nor negative. Because its right in between being positive and negative.

For example: On the number line, as you can see, the opposite of a positive number such as 1 is directly the opposite of -1. But zero has no opposite numbers so it is and always will just be a neutral "0"
