WebWrite each of the following functions as a composition of functions chosen from f, g, and h. A(x) = g ∘h(x) since g ∘h(x) = g(h(x)) = g(x2) = x2 −7 B(x) = h(g(x)) since h(g(x)) = h((x− … dot approved helmets for children

WebI will write the formulas at each step, using parentheses to indicate where the inputs should go: ( f ∘ g ) ( x) = f ( g ( x )) = f (− x2 + 5) = 2 ( ) + 3 = 2 (− x2 + 5) + 3 = −2 x2 + 10 + 3 = −2 x2 + 13 This final line, being as simplified as I can go, gives me my answer. ( f … WebAssuming 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. Thus: 𝑔 (𝑥 – 6 + 6) = 5 (𝑥 – 6) + 8 Which we reduce to: 𝑔 (𝑥) = 5𝑥 – 22 WebHow to Evaluate Function Composition When a is in the second set of parentheses. Ex. f (g(x)) Step 1. Plug in the inside function wherever the variable shows up in the outside function. The inside function is the input for the outside function. Step 2. Simplify the expression. (optional) Step 3. Plug in the input. city of spokane street obstruction permit
