Find functions $f(x)$ and $g(x)$ so the given function can be expressed as $h(x) = (f \circ g)(x)$. (Use non-identity functions for $f(x)$ and $g(x)$.) $h(x) = \sqrt{\frac{4x-3}{x+5}}$ $\{f(x), g(x)\} = \{\boxed{\phantom{x}}, \boxed{\phantom{x}}\}$

Warfarin (acid analyte, pKa 5) and codeine (basic analyte, pKa 8) are analyzed on a reverse-phase HPLC column. The mobile phase composition is 50:50 water:methanol, its pH is about 7 but it is not buffered. The results show low retention times, poor peak shape, and co-elution of both analytes. At the current pH, please show the proportion of both analytes found in both the mobile phase (MP) and stationary phase (SP). (Hint: Using a logarithmic rule of thumb) 10 : 90 Warfarin distribution in MP : SP ; 10 : 90 Codeine distribution in MP : SP 90 : 10 Warfarin distribution in MP : SP ; 90 : 10 Codeine distribution in MP : SP 99 : 01 Warfarin distribution in MP : SP ; 90 : 10 Codeine distribution in MP : SP 01 : 99 Warfarin distribution in MP : SP ; 10 : 90 Codeine distribution in MP : SP
