Math Problem Statement
A graphing calculator is recommended. For the limit lim x → 2 (x3 − 5x + 9) = 7, illustrate this definition by finding the largest possible values of 𝛿 that correspond to 𝜀 = 0.2 and 𝜀 = 0.1. (Round your answers to four decimal places.) 𝜀 = 0.2 𝛿 =
𝜀 = 0.1 𝛿 =

Formal definition of a limit: For f(x), lim_{x → a} f(x) = L if for every ε > 0, there exists a δ > 0 such that whenever 0 < |x - a| < δ, |f(x) - L| < ε.
Cubic function: f(x) = x^3 - 5x + 9
