Answer:

It should be C

Step-by-step explanation:

Substituting in a value of x,

4 * ( 1/2 )^x               4 * ( 1/2 )^x

= 4 * ( 1/2 )^ 2         = 4 * ( 1/2 )^ -2

= 4 * 1/4                  = 4 * 4

= 1                           = 16

C checks out, and all the other options don't equal to the values on the table.
