Question 2 of 10Use the function below to find F(4).F(x)=5•(-)*5OA. 16OB.O C.O D.518532514

Answer 1

Given:

`f(x)=5\cdot((1)/(2))^x`

f(4) means substitute x = 4 into the function

Hence,

`\begin{gathered} f(4)=5\cdot((1)/(2))^4 \\ f(4)=5*((1)/(2))^4 \\ f(4)=5*(1^4)/(2^4) \\ f(4)=5*(1)/(16) \\ f(4)=(5)/(16) \end{gathered}`

Therefore, the correct answer is OPTION A.
