Explain the words relation and function. Include in your explanation how the meanings of the two words differ. Give a real-world example of a relation that is not a function. Is it possible to give an example of a function that is not a relation? If so, give one, if not, explain why it is not possible.
y^2 = x
y is not a function of x, since there are two values of y for eacvh value of x>0
Any function is also a relation.
