What is the best description of the relation?
Pie

Answer:

The relation is <u>not</u> a function.

Step-by-step explanation:

A function is a relation in which no two ordered pairs have the same input  and different outputs. Whenever you're trying to determine whether a given relation is a function, observe whether each input corresponds with <u><em>exactly</em></u> one output.

In this case, the answer is no.  The input value of 10 corresponds with two output values, 4 and 20.  It only takes one input value to associate with more than one output value to be <u>invalid</u> as a function.

Therefore, the given relation is <em><u>not</u></em> a function.
