Which statement is true for a one-one function?

Answer and explanation

Correct answer: Different inputs have different outputs

Step 1: In a one-one function, two different inputs cannot have the same output. Step 2: So different inputs must give different outputs. Step 3: To test one-one, assume (f(a)=f(b)) and show (a=b).
