Question

Which expression is equivalent to (f + g)(4)?

Answer 1

We'll need to know what f(x) and g(x) are

Answer 2

Is it one of these?

Answer 3

f(4) + g(4)
f(x) + g(4)
f(4 + g(4))
4(f(x) + g(x))

Answer 4

Ah I see

I mean any guesses?

(f+g) is adding both equations where they both have 4 = x

(you'd want to split them and have both include 4)

Answer 5

o it would be the 3 1?

Answer 6

No no, you want 4 in g(x) and f(x)


Ex.

\((f*g)(7) = f(7) * g(7)\)
