Functions are a specific types of relations, where for every "input" there is onli one observation our "output", the "input" / X-value is the independent value and the "output" / Y-value is the dependent value, meaning that it varies alongside X.

First organize the pairs in a table:

As you can se for the input X=-8 there are two outputs Y=8 and Y= 6.

Since the function, by definition only has one value of Y per value of X, this relation is not a function.

Tell whether or not the relation is a function{(-8,8).(-8,6), (2. - 9), (3.-8), (7-5)O-example-1
