Respuesta :
[tex]f(3)=\frac{64}{3}[/tex]
The correct answer is an option (A)
What is function?
- "It defines a relation between input and output values."
- "In function, for each input there is exactly one output."
For given question,
We have been given a function [tex]f(x) =\frac{1}{3} 4^x[/tex]
We need to find f(3)
We need to find the value of the function at x = 3
Substitute x = 3 in given function.
[tex]\Rightarrow f(x) =\frac{1}{3} 4^x\\\\\Rightarrow f(3) =\frac{1}{3} 4^3\\\\\Rightarrow f(3) =\frac{1}{3} 64\\\\\Rightarrow f(3) =\frac{64}{3}[/tex]
Therefore, [tex]f(3)=\frac{64}{3}[/tex]
The correct answer is an option (A)
