Question

Is this True or False ?

Answer 1

Option B True

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
