Question

- Consider the functions f(x) = 2(x − 5) and g(x) = 3x. What is the value of (f + g)(2)?

- Consider the functions f(x) = 2(x − 3) and g(x) = 3x. What is the value of (f − g)(3)?

Answer 1

(f+g)(x) = f(x)+g(x)

Answer 2

I'm still confused....

Answer 3

which part?
You can expand (f+g)(x) as f(x)+g(x). You know both the functions just add values and you have ur answer
