A quality control technician is using the equation $x + y^2 = 3$ to model the relationship between a machine's input setting $x$ and its output pressure $y$. When the technician sets the input to $x = 2$, the equation simplifies to $y^2 = 1$, indicating that the pressure $y$ could be either 1 or -1. Why does this result prove that $y$ is NOT a function of $x$?

A manufacturing technician is using the equation $x + y^2 = 3$ to model the relationship between a machine's input setting $x$ and its vibration level $y$. To determine if this model represents a function, match each step of the analysis with its corresponding action or result.

A technician is evaluating a machine's calibration model defined by the equation $x + y^2 = 3$. True or False: When the technician substitutes the value $x = 2$ into this model, the equation yields exactly one possible output value for $y$.

Analyzing a Temperature-Pressure Model

A technician is evaluating a manufacturing model represented by the equation $x + y^2 = 3$. Arrange the steps in the correct sequence to demonstrate why this relationship does not define a function, based on the standard algebraic analysis.
