1. The problem is to find the values of $y$ for given values of $x$: $-2.3$, $-2.2$, $-2.1$, $-1.9$, $-1.8$, and $-1.7$. 2. However, the function or equation relating $x$ and $y$ is not provided, so we cannot calculate $y$ values without it. 3. To solve such problems, you need a formula or function $y=f(x)$ that defines $y$ in terms of $x$. 4. Once the function is known, substitute each $x$ value into the function and simplify to find the corresponding $y$. 5. Please provide the function or equation for $y$ in terms of $x$ to proceed with calculations.
