Two real-valued functions, f(x) and g(x), are defined as f(x) = x2 + 6x + 9 and g(x) = x2 – 9. Find the results of combining these functions.
Tiles
(f + g)(x)
(f – g)(x)
(f × g)(x)
(f ÷ g)(x)
Pairs
6(x + 3)

2x(x + 3)

(x+3)(x−3)

x4 + 6x3 – 54x – 81

tiles?

misty1212 · Answer

$$f(+g)(x)=f(x)+g(x)=x^2+x+9+x^2-9$$ combine like terms
others are similar to that one

anonymous · Answer

i have to match those tiles to the pairs. ex. (x+3)(x-3)=(f/g)(x)
