Question: An oceanographer models the salinity of a water sample at depth $ x $ (in meters) with a quadratic polynomial $ s(x) $ such that $ s(1) = 34 $, $ s(2) = 36 $, and $ s(3) = 42 $. Find $ s(0) $.

**An oceanographer models the salinity of a water sample at depth $ x $ (in meters) with a quadratic polynomial $ s(x) $ such that $ s(1) = 34 $, $ s(2) = 36 $, and $ s(3) = 42 $. Find $ s(0) $** Ever wondered how salt levels shift deep underwater—and why scientists turn to math to track these invisible changes? A growing number of researchers are modeling ocean salinity with precise mathematical functions, including quadratic polynomials, to capture natural gradients and support climate and marine studies. One key challenge is determining a polynomial’s behavior at specific depths using real-world data points. This question illustrates how basic function modeling delivers actionable insights—bridging environmental science with data-driven precision. **Why This Question Is Trending Among Curious Minds in the U.S.** Recent interest in ocean salinity models aligns with broader public and scientific attention to climate dynamics, ocean health, and data-informed environmental stewardship. Salinity influences current patterns, marine ecosystems, and global water cycles—increasingly studied in climate adaptation planning. Plotting salinity changes across depth using quadratic functions enables scientists to visualize underlying patterns in complex marine systems. This relevance makes the question resonate with readers exploring climate science, environmental careers, or data-driven research—especially those seeking accessible yet authoritative explanations.
