Theorem limciccioolb 44422

Description: The limit of a function at the lower bound of a closed interval only depends on the values in the inner open interval. (Contributed by Glauco Siliprandi, 11-Dec-2019.)

**Hypotheses**
Ref	Expression
limciccioolb.1	⊢ (𝜑 → 𝐴 ∈ ℝ)
limciccioolb.2	⊢ (𝜑 → 𝐵 ∈ ℝ)
limciccioolb.3	⊢ (𝜑 → 𝐴 < 𝐵)
limciccioolb.4	⊢ (𝜑 → 𝐹:(𝐴[,]𝐵)⟶ℂ)

**Assertion**
Ref	Expression
limciccioolb	⊢ (𝜑 → ((𝐹 ↾ (𝐴(,)𝐵)) lim_ℂ 𝐴) = (𝐹 lim_ℂ 𝐴))

Proof of Theorem limciccioolb Dummy variable 𝑥 is distinct from all other variables.
