Answer:
Option B True
Step-by-step explanation:
we know that
A function relates each element of a set (input) with exactly one element of another set (output)
1) "...each element..." means that every element in X (input) is related to some element in Y (output)
2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input
therefore
f(x) is a function
