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

WebFeb 22, 2024 · Since f(x) is "2x + 1" and g(x) is "x2 - 7" then f(x) + g(x) [which is the same as (f + g)(x)] is "2x + 1" + "x2 - 7" which is 2x + 1 + x2 - 7 or x2 + 2x - 6. So (f + g)(x) = … WebIt follows that f (g ( {3}))=f ( {29})= {86} f (g(3)) = f (29) = 86. Finding the composite function In the above example, function g g took 3 3 to 29 29, and then function f f took 29 29 to 86 86. Let's find the function that takes 3 3 directly to 86 86. To do this, we must compose the …

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.
