Which expression is equivalent to (f g) (5) ?

f (5) times g (5)

f (5) + g (5)

5 f (5)

5 g (5)

Option A.

Step-by-step explanation:

Expression given in the question is (f g) (5).

We know when two functions are f (x) and g (x) then (f g) (x) represents the multiplication of two functions.

(f g) (x) = f (x).[g (x) ]

For x = 5

(f g) (5) = f (5). g (x)

It may be represented by the operation as

(f g) (5) = f (5) * g (x)

Therefore, option A. will be the answer.
