Answer:

B

Step-by-step explanation:

A function is a relation in which each y-value has a unique x-value. This means that in a function x-values should never repeat. In both A and C one x-value repeats, meaning they cannot be functions. However, in table B x-values don't repeat, only y-values which is allowed by the definition of function.

     5         =           1      ⇒   x - centimeters of the poster

     x                     10

<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>

5 * 10 = x,

x =<em> 50 centimeters of the poster </em>
