which expression is equivalent to (f + g)(4)?\no f(4) + g(4)\no f(x) + g(4)\no f(4 + g(4))\no 4(f(x) + g(x))
which expression is equivalent to (f + g)(4)?\no f(4) + g(4)\no f(x) + g(4)\no f(4 + g(4))\no 4(f(x) + g(x))
Answer
Explanation:
Step1: Recall function - addition rule
By the definition of the sum of two functions, for any real - number (x), ((f + g)(x)=f(x)+g(x)).
Step2: Substitute (x = 4)
When (x = 4), we substitute (x) into the equation ((f + g)(x)=f(x)+g(x)). So ((f + g)(4)=f(4)+g(4)).
Answer:
A. (f(4)+g(4))
