Web3. Let x ∈ R satisfy x 7 + 5 x 2-3 = 0. Then x is not a rational number. Solution We use proof by contradiction. Suppose x 7 + 5 x 2-3 = 0 and x is rational, so we can write x = a b where … WebThus, it can be clearly observed that the range of f is the set of all real numbers less than 2.. i.e., range of f = (–`oo`, 2). Alter: Let x > 0. ⇒ 3x > 0. ⇒ 2 –3x < 2. ⇒ f(x) < 2. ∴Range of f = …
