Compute the missing data in the table for the following exponential function f(x)=(3)^x

slega [8]

ANSWER

The correct answer is B.

$27$

EXPLANATION

The give function is
$f(x) = {3}^{x}$

The missing data occurs at
$x = 3$

We substitute
$x = 3$
into the given function and simplify.

This implies that,
$f(3) = {3}^{3}$

This gives us,

$f(3) = 3 \times 3 \times 3$

This simplifies to,

$f(3) = 27$
Therefore the missing data is 27
