Final answer:

By substituting x=3 into the given function f(x) = 1/(2x), we calculate the value f(3) = 1/6, making (a) 1/6 the correct answer.

Step-by-step explanation:

To find the indicated value for f(x) = 1/(2x) when x = 3, we follow a straightforward substitution process. Plug the value of x into the function and simplify the expression to find the result:

f(3) = 1 / (2*3) = 1 / 6

Through this simple calculation, we reach the value 1/6 for f(x) when x equals 3. This makes option (a) 1/6 the correct choice from the provided selections.

It's important to remember that when working with functions, particularly ratios or fractions, you substitute the given x-value directly into the equation wherever x appears and then perform the normal arithmetic operations to simplify and arrive at your answer.
