Answer: Option a:


(f * g) (x) = 2x

Explanation:

The expression
(f * g) (x) refers to the multiplication of two functions f and g.

In this case we know that the functions are:


f (x) = x\\\\g (x) = 2

Then you must multiply the two functions we get.


(f * g) (x) = f (x) * g (x)\\\\(f * g) (x) = 2 * x\\\\(f * g) (x) = 2x

The correct answer is option a.
