Polynomial: c₃x³ + c₂x² + c₁x + c₀ (set unused coefficients to 0)

For any polynomial function, direct substitution always works because polynomials are continuous everywhere — there’s no 0/0 case to worry about, unlike rational functions. Full reasoning, including how to handle indeterminate forms, in the Limits and Derivatives chapter guide.
