Hello. What kind of help do you need? That is, where did you get stuck?
Are you able to calculate the value of f(3) and the value of g(3) separately? If so, then add those two numbers (for part a). If you don't understand the symbols f(3) and g(3) -- or how to find their values -- please let us know.
(f+g)(3) means f(3) + g(3)
Likewise, (f−g)(3) means f(3) - g(3)
(fg)(3) = f(3) ∙ g(3)
(f/g)(3) = f(3) / g(3)
If you've started, please show the work you've tried so far.
