MAT 243 Online Written Homework Assignments for Week 6/15 1. Are the two functions ? and ? defined by ?: {0,1} → {0,1}; ?(?) = ? 2 ?: {0,1} → {0,1}; ?(?) = ? equal or not equal? Explain. ? and ? are equal. Their domain and codomain are equal and ?(?) = ?(?) for ALL ? in the common domain, since ?(0) = ?(0) = 0 and ?(1) = ?(1) = 1. 2. Is the function ?: [0,1] → [1,5]; ?(?) = 4? + 1 bijective? Prove or disprove. Proof: . 3. Is the function ?: [−1,1] → [0,1]; ?(?) = ? 2 bijective? Prove or disprove. 2 . 4. Prove or disprove: the floor function is additive, i.e. whenever ? and . 5. Find all real solutions ? of the equation ⌊2? − 1⌋ = 5 . Show your work. Give your solution set as an interval.
