Quenching is the process of immersing a hot metal object in a bath for a specified time to obtain certain properties such as hardness. A copper sphere $25mm$ in diameter, initially at $300C,$ is immersed in a bath at $0C.$ The following table gives measurements of the sphere's temperature versus time. Find a functional description of these data. Plot the function and the data on the same plot.

$\backslash$table$[[$Time $(s),0,1,2,3,4,5,6],[$Temperature $(C),300,150,75,35,12,5,2]]$
