Question

F = {(-1, 2), (3, 2), (4, 2), (0, 2)} Is F a function and why/why not?

Answer 1

Answer:

Yes, no two ordered pairs in this list have the same first coordinate

Step-by-step explanation:

we know that

A function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

That means that there can be only one ordered pair with the same value of x.

therefore

In this problem F is a function, because all the ordered pairs of the list don't have the same first coordinate
