Is the Given Function Injective?
A function is injective (or one-to-one) if different inputs give different outputs. In symbols, is injective if whenever ≠, then . To show that a function is not injective, find ≠ such that . Graphically, this means that a function is not injective if its graph contains two points with different values and the same value.
