efine G: β β β by the rule G(x) = 2 β 3x for each real number x. Prove that G is onto. Proof that G is onto: Let y be any real number. (Scratch work: On a separate piece of paper, solve the equation y = 2 β 3x for x. Enter the resultβan expression in yβin the box below.) x = To finish the proof, we need to show (1) that x is a real number, and (2) that G(x) = y. Now sums, products, and differences of real numbers are real numbers, and quotients of real numbers with nonzero denominators are also real numbers. Therefore, x is a real number. In addition, according to the formula that defines G, when G is applied to x, x is multiplied by 3 and the result is subtracted from 2. When the expression for x (using the variable y) is multiplied by 3, the result is 3x = . And when the result is subtracted from 2, we obtain 2 β 3x = . Thus G(x) = y. Hence, there exists a number x such that x is a real number and G(x) = y.
