It looks like you're working with a function $Y(x)$ and evaluating it at different points. Could you clarify what you're trying to determine? Are you looking for interpolation, extrapolation, or something else?

If you want to find $x$ for which $Y(x) = 1.158$, you might need interpolation between given points. Let me know how you'd like to proceed!

Tip: When working with interpolation, always check if the data follows a linear or nonlinear trend!
