A logistics company uses the function $f(x) = 3x^2 + 2x - 15$ to model the net profit (in hundreds of dollars) based on the number of additional delivery trucks, $x$, added to their fleet. According to the provided examples for this function, what is the value of $f(3)$?

A quality assurance engineer is validating the logic of a new testing software that uses the function $f(x) = 3x^2 + 2x - 15$ to model material stress. To verify the software's calculations, the engineer manually evaluates the function for a stress factor of $x = -5$. Based on the standard procedure, arrange the following steps in the correct order to recall the evaluation of $f(-5)$.

A business analyst uses the function $f(x) = 3x^2 + 2x - 15$ to model monthly profit variance. To determine the baseline variance when the adjustment factor $x$ is 0, the analyst evaluates the function. According to the evaluation examples provided for this model, the resulting value of $f(0)$ is ____.

A structural engineering firm uses the quadratic function $f(x) = 3x^2 + 2x - 15$ to model stress levels on a beam based on a process adjustment factor $x$. According to the firm's standard reference table for this model, match each adjustment factor $x$ with its corresponding stress result $f(x)$.

A systems engineer uses the mechanical stress model $f(x) = {}3x^2 + 2x - 15$ to monitor equipment health. According to the technical reference manual for this model, evaluating the function for an adjustment factor of $x = -5$ results in a stress value of 50.
