    To evaluate a function, simply replace (substitute) the function's variable with the indicated number or expression. A function is represented by f (x) = 2x + 5. Find f (3). To find f (3), replace the x - value with 3. thats how you evaluate a function but i dont know the answer i just gave you an example.
