To find F(4), you simply plug 4 in for x. That means multiplying 5 by 1/2x to the 4th power. That comes out to .3125, or D. (5/16)

Answer:

The answer is the option D

\((\frac{5}{16})\)

Step-by-step explanation:

we have

\(f(x)=5(\frac{1}{2})^{x}\)

we know that

To find \(f(4)\)

substitute the value of \(x=4\) in the function

so

\(f(4)=5(\frac{1}{2})^{4}\)

\(f(4)=5(\frac{1}{16})\)

\(f(4)=(\frac{5}{16})\)
