Question

If f(x) = x and g(x) = 2, what is (f*g)(x)
a:2x
b:2
c:x+2
d:x/2

Answer 1

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.
