Theorem iccshift 46735

Description: A closed interval shifted by a real number. (Contributed by Glauco Siliprandi, 11-Dec-2019.)

**Hypotheses**
Ref	Expression
iccshift.1	⊢ (𝜑 → 𝐴 ∈ ℝ)
iccshift.2	⊢ (𝜑 → 𝐵 ∈ ℝ)
iccshift.3	⊢ (𝜑 → 𝑇 ∈ ℝ)

**Assertion**
Ref	Expression
iccshift	⊢ (𝜑 → ((𝐴 + 𝑇)[,](𝐵 + 𝑇)) = {𝑤 ∈ ℂ ∣ ∃𝑧 ∈ (𝐴[,]𝐵)𝑤 = (𝑧 + 𝑇)})

Distinct variable groups: 𝑤,𝐴,𝑧 𝑤,𝐵,𝑧 𝑤,𝑇,𝑧 𝜑,𝑧 Allowed substitution hint: 𝜑(𝑤)

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