f(18) = 3

Value of x when f(x) = 6: x = 3

Step-by-step explanation:

f(x) means “the output of the function f when the input is x.” Essentially, f(x) is the same as the output, while the "x" inside the parenthesis is the input.  

Solely using the given table:

Evaluate f(18):  The input here is x = 18.  It is asking for the output, or the f(x). If you look at your given table, when x = 18, your f(x) = 3. So, f(18) = 3.

Determine x when f(x) = 6:

This time, it gives you the value of the f(x), which is 6. It is now asking you to find out what the input value is (or the value of x when f(x) = 6). The table indicates that the f(x) that has a value of 6 is paired with an x-value of 3. Therefore:  the value of x when f(x) = 6 is 3.
