An operations analyst is using the equation $y - x^2 = 2$ to model the relationship between the number of units produced ($x$) and the total production time ($y$). To confirm that this equation defines $y$ as a function of $x$, the analyst isolates $y$ and observes the results. According to the definition of a function, why does this specific equation define a function?

A production planner is evaluating a resource mapping formula given by the equation $y - x^2 = 2$. To determine if this mapping qualifies as a function, the planner follows a specific logical process. Arrange the following steps in the correct order to recreate the proof that this equation defines $y$ as a function of $x$.

An automation engineer is evaluating a sensor's performance model. The relationship between the input signal $x$ and the output voltage $y$ is given by the equation $y - x^2 = 2$. To ensure the sensor generates predictable results, the engineer must verify that the model defines a function. Match each component of the engineer's analysis to its correct description based on the provided equation.

Verifying a Maintenance Cost Model

A junior business analyst uses the equation $y - x^2 = 2$ to model a delivery fleet's weekly maintenance cost, where $x$ represents the fleet's age in years (the independent variable) and $y$ represents the maintenance cost in thousands of dollars. To verify that cost is a function of fleet age, the analyst isolates $y$ to get the equation $y = x^2 + 2$. Under the definition of a function, for any real value substituted for the age $x$, squaring it and adding 2 yields exactly ____ corresponding
