ANSWER
The correct answer is B.
[tex]27[/tex]
EXPLANATION
The give function is
[tex]f(x) = {3}^{x} [/tex]
The missing data occurs at
[tex]x = 3[/tex]
We substitute
[tex]x = 3[/tex]
into the given function and simplify.
This implies that,
[tex]f(3) = {3}^{3} [/tex]
This gives us,
[tex]f(3) = 3 \times 3 \times 3[/tex]
This simplifies to,
[tex]f(3) = 27[/tex]
Therefore the missing data is 27
