------------------------------------------------ If [tex]f(x)=3^{(x+4)}[/tex], find [tex]f(2)[/tex].

A. 729
B. 243
C. 81
D. 18

Answer :

To find [tex]\( f(2) \)[/tex] for the function [tex]\( f(x) = 3^{(x+4)} \)[/tex], you follow these steps:

1. Start with the given function: [tex]\( f(x) = 3^{(x+4)} \)[/tex].

2. Substitute [tex]\( x = 2 \)[/tex] into the function:
[tex]\[
f(2) = 3^{(2+4)}
\][/tex]

3. Simplify the exponent:
[tex]\[
f(2) = 3^6
\][/tex]

4. Calculate [tex]\( 3^6 \)[/tex]:
- First, calculate [tex]\( 3^3 = 3 \times 3 \times 3 = 27 \)[/tex].
- Then, calculate [tex]\( 3^6 = 27 \times 3 \times 3 = 729 \)[/tex].

So, [tex]\( f(2) = 729 \)[/tex].

The correct answer is 729.
