In two or more complete sentences describe whether or not the given relation represents a function.

vichka [17]

To be a function each x-value (input) should have only one y-value (output). Here you can see when x=2 it has an output of either 5 or 1. Therefore, the relation is NOT a function.

elixir [45]

ANSWER

The answer is

$\frac{1}{27}$

EXPLANATION

The given expression is

${3}^{ - 3}$

Use the negative index property;

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this property to get:

${3}^{ - 3} = \frac{1}{ {3}^{3} }$

This gives us:

${3}^{ - 3} = \frac{1}{3 \times 3 \times 3 }$

${3}^{ - 3} = \frac{1}{27}$

The correct option is B.
