ANSWER
[tex](f \times g)(x) = 2x[/tex]
EXPLANATION
The given functions are
[tex]f(x) = x[/tex]
and
[tex]g(x) = 2[/tex]
We want to find
[tex](f \times g)(x) = f(x) \times g(x)[/tex]
This means we need to multiply the two functions to get:
[tex](f \times g)(x) = x \times 2[/tex]
This will simplify to
[tex](f \times g)(x) = 2x[/tex]
The correct answer is A
