For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)

The temperature of a chemical solution is originally 21 ? c . a chemist heats the solution at a constant rate, and the temperature of the solution 75 ? c after 1212 12 minutes of heating. the temperature, tt t , of the solution in ? c is a function of x , the heating time in minutes. write the function's formula.

How do you find the rate of change using a graph?
