I'm a bit confused.. Is this supposed to be asking a question about Combining Like Terms or is it like, telling what it is or something. I'm just clueless lol, It's good if your just telling people what it is if anyone needs help with it though! Not many people do that!
A={a,b,c}, B={9,16,25}, and f={(a,9),(b,16),(a,25)}. True or false, f is a function from A to B?

Answer: False</h3>
Explanation:
The input x = a leads to multiple outputs y = 9 and y = 25 at the same time. This is due to the points (a,9) and (a,25) in the set f.
A function can only be possible when any x input leads to exactly one y output only. You'd need to get rid of either (a,9) or (a,25) to make this a function.
