Show that f is a one to one function
Algebraic Test. Definition 1. A function f is said to be one-to-one (or injective) if f(x1) = f(x2) implies x1 = x2. Lemma 2. The function f is one-to-one if and only if. ,To show that f is 1-1, you could show that f(x)=f(y)⟹x=y. So, for example, for f(x)=x−3x+2: Suppose x−3x+2=y−3y+2. ,A function for which every element of the range of the function corresponds to exactly one element of the domain. One-to-one is often written 1-1. Note: y = f(x) is a ... ,Examples of One to One Functions. Example 1. Show algebraically that all linear functions of the form f(x) = a x + b , with a ≠ 0, ... ,
