A marine biologist is monitoring the environmental conditions of a coastal pool. The temperature TTT (in degrees Celsius) and the salinity SSS (in g/L) of the pool at time ttt hours after high tide are modeled by the parametric equations
T=3t+2,S=4t+32t+1,t>0T = \frac{3}{t} + 2, \quad S = \frac{4t + 3}{2t + 1}, \quad t > 0T=t3+2,S=2t+14t+3,t>0
Show that the relationship between salinity and temperature can be written in the form S=g(T)S = g(T)S=g(T), where ggg is the function
g(T)=aT+bcT+d,T>kg(T) = \frac{aT + b}{cT + d}, \quad T > kg(T)=cT+daT+b,T>k
and a,b,c,da, b, c, da,b,c,d, and kkk are integers to be found.
Hence, or otherwise, state the range of ggg.
