Is this a funtion? please help

No, it is not

Step-by-step explanation:

Here, we want to check if what we have is a function

For a relation to be a function, the mapping must be one to one or many to one

This mean, for every x there must be one y or for every y, there must can be multiple x

But never is it that there are many y for a single x

Looking at the value 0

on the domain, we can see -2 and 1 as the values

Thus, this is not a function

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
