which expression is equivalent to (fg)(5)?\n○ f(5)×g(5)\n○ f(5)+g(5)\n○ 5f(5)\n○ 5g(5)
which expression is equivalent to (fg)(5)?\n○ f(5)×g(5)\n○ f(5)+g(5)\n○ 5f(5)\n○ 5g(5)
Answer
Explanation:
Step1: Recall function - product definition
The notation ((fg)(x)) is defined as (f(x)\times g(x)) for any value of (x) in the domain of both (f) and (g).
Step2: Substitute (x = 5)
When (x = 5), ((fg)(5)=f(5)\times g(5))
Answer:
A. (f(5)\times g(5))
