To answer this item, note that what needs to be done is to substitute -4 to all x's in the equation. That is,
                     F(x) = 2^x
will become,
                     F(-4) = 2^(-4) = 1/16 or 0.0625

Answer:

The value of F(-4) in the expression F(x) = 2^x is

= 16

Step-by-step explanation:

Step one :

To solve the problem we we need to impute the given value for x into the expression F(x) = 2^x

Step two

The given value F(-4), says that x=-4

If we properly and correctly substitute this value into the expression we have

Step three

F(-4) = 2^4=2222

F(-4)=44

F(-4)=16

Hence the value of F(-4) in the expression F(x) = 2^x is

16
