Challenge Problems
Push your limits with challenges.
Question 1
Design a function with a set domain: {1, 2, 3} and a co-domain of {x, y, z}. If f(1)=x, f(2)=y, f(3)=z, discuss the range and the function’s implications.
💡 Hint: Identify how outputs relate to inputs and discuss uniqueness.
Question 2
Create a function with domain {0, 1, 2} but restrict its outputs only to positive integers. Examine the co-domain, range, and implications for the function.
💡 Hint: Consider the imposed limitations on outputs and how that alters their relationships.
