Question

Use the function below to find F(3). F(x) = 3x

Answer 1

The value of F(3) = 27.

Step-by-step explanation:

Step 1:

F(x) is dependent on the value of x.

So x is independent while F(x) is dependent on x i.e. the value of F(x) depends on the value of x.

Step 2:

F(x) = $3^{x}$, if we have the x's value we can calculate the F(x)'s value.

Here the value of x is given as 3 so F(x) when x equals 3 can be calculated.

$F(x) = 3^{x} , F(3) = 3^{3} = 27.$

So F(3) = 27.
