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?

Sagot :

Answer: False

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.
