Question

Which expression is equivalent to mc003-1.j pg? mc003-2.jp g mc003-3.j pg mc003-4.j pg mc003-5.jp g

answer is A

Answer 1

Answer:

f(5)·g(5)

Step-by-step explanation:

fg(x) = f(x)·g(x), so

fg(5) = f(5)·g(5)

Answer 2

Answer:

Option A.

Step-by-step explanation:

The given expression is

$(fg)(5)$

According to the composition of functions, if f(x) and g(x) are two functions, then

$(fg)(x)=f(x)\cdot g(x)$

Substitute x=5 in the above formula, to find the expression which is equivalent to the given expression.

$(fg)(5)=f(5)\cdot g(5)$

Therefore, the correct option is A.
