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. WebMar 4, 2024 · So a verbal description of the composed f ∘ g ∘ h as a sequence of steps might be: Subtract 1 Double Square Add 1 So in symbols we might describe this process thus: x → x −1 → 2(x −1) → (2(x − 1))2 → (2(x −1))2 +1 So: (f ∘ g ∘ h)(x) = f (g(h(x))) (f ∘ g ∘ h)(x) = (2(x − 1))2 + 1 (f ∘ g ∘ h)(x) = 4(x2 − 2x +1) +1 (f ∘ g ∘ h)(x) = 4x2 − 8x + 4 + 1

WebFor example, if f(x) = x + 1, and g(x) = x^2, finding f(g(x)) wouldn't most likely be regarded as hard, since you can simply substitute the x^2 in to get f(g(x)) = x^2 + 1 However, if … WebIf f(x) is a product of several factors, any constants (factors in the product that do not depend on x) can be omitted. For example, let f(x) = 6x 4 − 2x 3 + 5, and suppose we wish to simplify this function, using O notation, to describe its growth rate as x approaches infinity. This function is the sum of three terms: 6x 4, −2x 3, and 5.
