Evaluate the exponential function ƒ(x) = (1/2)^x x      -4    -1    0      1      3 ƒ(x) 16    ?     1    1/2    1/8 which value completes this table? a.12 b.8 c.4 d.2

For this case we have the following exponential function:
 
 Evaluating the function for x = -1 we have:
 
 By power properties we can rewrite the function.
 We have then:
 
 
 
 
 The value that completes the table when x = -1 is:
 
 D. 2

The answer is

Idon’t feel like doing the math but you need to do 2.24 divided by 7
