If you have an expression of the form O(f(n) + g(n)), you can almost always rewrite it as O(f(n)) or O(g(n)) depending on which is bigger. The same goes for Ω or Θ. O(c f(n)) = O(f(n)) if c is a constant. You should never have a constant inside a big O.Well, h(x) is f(g(x)), and f(g(x)) is simply the function f, but you replace the x's in the equation with g(x). Let's see what that is: h(x) = f(g(x)) = g(x) + 5/3 = -2x 2 + 5/3. So the question said to find (read: make up) two functions f and g so that f(g(x)) = -x 2 + 5/3 - x 2. Welp, we found those two functions. They are g(x) = -x 2 and f(x ... Assuming that 𝑔 is a linear polynomial function in 𝑥. Then we have: 𝑔 (𝑥 + 6) = 5𝑥 + 8. The variable we use doesn't matter, so to avoid confusion, we will write this functional equation in 𝑘 instead of 𝑥: 𝑔 (𝑘 + 6) = 5𝑘 + 8. Since 𝑘 ∈ ℝ, we let 𝑘 = 𝑥 – 6 where 𝑥 ∈ ℝ.
