Here is how I see it: (1) 2x > x^2 The only number that satisfies this inequality is 1 (2 > 1). A negative number will not satisfy. For example: 2(-1) > (-1)^2 = -2 > 1...which is incorrect. Because the only number that satisfies is 1, then the answer is sufficient. (2) x could equal 0 or a negative...
