Define a function f on a set of real numbers as follows. ffx)= 3X - 1. for each real number x 0 Is fis one-to-one? To answer this question, let x, and x, be any nonzero real numbers such that f(x,) = f(x,). Use the definition of f to rewrite the left-hand side of this equation. (Enter the answer as an expression in x,) Then use the definition of f to rewrite the right-hand side of f(x,) = f(x). (Enter the answer as an expression in x.) Equate the expressions obtained for the left- and right-hand sides of f(x,) = f(x,), and simplify the result completely. The result is the following equation. x = Therefore, f is one-to-one Need Help? Read It
