A function f(x) is defined on a set of real numbers x not equal to 0 as: f(x) = (2x +1)/x. Is f(x) one to one?© BrainMass Inc. brainmass.com March 4, 2021, 5:36 pm ad1c9bdddf
To show f(x) is one to one, we only need to prove that if f(x)=f(y), then x=y. In ...
This shows how to determine if a function is one-to-one.
