Final answer:
To evaluate the function at 1/a, substitute 1/a into the function wherever there is an 'x'.
Step-by-step explanation:
The task is to evaluate the function at the given values 1/a. In this case, let's assume the function is f(x).
Evaluating the function at 1/a means substituting the value 1/a into the function wherever there is an 'x'.
So, the answer would be f(1/a).
