which expression is equivalent to (f + g)(4)?\n○ f(4) + g(4)\n○ f(x) + g(4)\n○ f(4 + g(4))\n○ 4(f(x) + g(x))
which expression is equivalent to (f + g)(4)?\n○ f(4) + g(4)\n○ f(x) + g(4)\n○ f(4 + g(4))\n○ 4(f(x) + g(x))
Answer
Explanation:
Step1: Recall function - addition definition
By the definition of the sum of two functions, ((f + g)(x)=f(x)+g(x)) for all (x) in the domain of both (f) and (g).
Step2: Substitute (x = 4)
When (x = 4), we have ((f + g)(4)=f(4)+g(4)).
Answer:
A. (f(4)+g(4))
