Answer: Option a:
[tex](f * g) (x) = 2x[/tex]
Step-by-step explanation:
The expression [tex](f * g) (x)[/tex] refers to the multiplication of two functions f and g.
In this case we know that the functions are:
[tex]f (x) = x\\\\g (x) = 2[/tex]
Then you must multiply the two functions we get.
[tex](f * g) (x) = f (x) * g (x)\\\\(f * g) (x) = 2 * x\\\\(f * g) (x) = 2x[/tex]
The correct answer is option a.
