Rewrite the function in the form y=a(1+r)^t of y=a(1-r)^t. Then state the growth of or decay rate. Y=a(8)^t/2

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.
