Question

Use the function below to find F(4)

F(x) = 5 (1/3)^x

Answer 1

If f(x)=5(1/3)^x and x=4 then:

f(4)=5(1/3)^4

f(4)=5/(3^4)

f(4)=5/81

Answer 2

Answer:

$f(4)=\frac{5}{81}$

Step-by-step explanation:

$f(x)= 5(\frac{1}{3} )^x$

We need to find f(4) using the given function f(x)

f(4) means x is 4

To find f(4) replace x with 4

$f(x)= 5(\frac{1}{3} )^x$

$f(4)= 5(\frac{1}{3} )^4$

$f(4)= 5(\frac{1}{3^4})$

$f(4)= 5(\frac{1}{81})$

$f(4)=\frac{5}{81}$
