For f x 2x+1 and g x x2-7 find f/g x

WebExample: (x+1/x)2 That function can be made from these two functions: f (x) = x + 1/x g (x) = x 2 And we get: (g º f) (x) = g (f (x)) = g (x + 1/x) = (x + 1/x)2 This can be useful if the original function is too complicated to work on. Summary "Function Composition" is applying one function to the results of another. WebWe need to find G of X G F F of X and F of G of X. Given the functions F of X and G fx. So for the first one we're going to replace all the exes and G fx with F of X. So we have negative too divided by three Divided by the absolute value of five -X. So this becomes negative two divided by three, two x 2 by the absolute 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. Thus: 𝑔 (𝑥 – 6 + 6) = 5 (𝑥 – 6) + 8 Which we reduce to: 𝑔 (𝑥) = 5𝑥 – 22

Inverse Function Theorem If y = g (x) is the inverse of f (x), then g' (x) = 1 / f ' (g (x)). Since, f (x) = 3x 3 + 2x + 1, it follows that f ' (x) = 9x 2 + 2.
