An engineering firm uses the quadratic function $f(x) = 3x^2 - 2x + 1$ to calculate the structural load at a specific point $x$. When evaluating this function for a position of $x = -1$, which of the following expressions correctly represents the substitution step as described in the evaluation procedure?

A quality assurance analyst is documenting the standard operating procedure for manually validating a quadratic prediction model, defined by the function $f(x) = 3x^2 - 2x + 1$. Arrange the computational steps in the exact order required to evaluate this model for an input value of 3, following the order of operations provided in the standard procedure.

A software developer is verifying unit tests for a calculation module defined by the quadratic function $f(x) = 3x^2 - 2x + 1$. Match each test input or variable for $x$ with its correctly simplified output or symbolic expression as defined in the standard procedure.

A small business owner uses the quadratic function $f(x) = 3x^2 - 2x + 1$ to calculate shipping surcharges based on the weight $x$ of a package. True or False: According to the standard evaluation procedure, substituting a variable such as $t$ for the input $x$ will result in a numerical constant rather than an algebraic expression.

Negative Substitution Protocol in Function Evaluation

A quality control auditor is reviewing the manual calculation steps for a risk assessment model defined by the function $f(x) = 3x^2 - 2x + 1$. According to the standard evaluation guidelines, when replacing the input $x$ with a negative value such as $-1$, the auditor must use ____ around the substituted value to properly preserve the negative signs.
