WebThen 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 ... WebAlgebra: Functions, Domain, NOT graphing Section. Solvers Solvers. Lessons Lessons.
