Explanation: This is a Multiple Choice, Select One GRE Quant problem. It involves evaluating a quadratic function by substituting a given value. For f(x) = 2x^2 - 5x + 1, substitute x = 3: f(3) = 2*(3)^2 - 53 + 1 = 29 - 15 + 1 = 18 - 15 + 1 = 4. This direct computation follows the order of operations. The value 4 satisfies the requirements because it accurately results from plugging in x = 3 into the function. A representative incorrect option like 7 (choice C) might result from an arithmetic slip, such as computing 29 - 53 + 1 as 18 - 15 + 4 or misadding. This fails to correctly perform the subtraction and addition steps.
