I keep getting stuck on every question so I'm behind on homework. This is supposed to use the difference quotient with limits so I did lim h->0 of [S(23+h) - S(23)]/h and kept going to plug in the x-value of 2005-1982=23 but then the numerator doesn't have all h's since the constant doesn't cross out.

I got until -11558.65 - 345.4h - 8.9h^2 + 0.95x^3 + 2.85x^2h + 2.85xh^2 + 0.95h^3. I feel like there's something I'm not understanding in the theory behind this problem but I'm not sure what.
