    Cooling the silly coffee !!!!! emmidiate help Due in a few Hours

    test y=ax^n and y=Ae^kx
    1). i need to investigate a power model in the form y=ax^n by plotting my raw data and log x vs log y
    2). i need to investigate a exponential modle in the form y=Ae^kx by plotting the raw data and x vs log y

    i now need to use graphs and correlation coefficients to determine the equation of the model that fits your Data.?????

    how do i find the equation... my text book only gose briefly and i missed the class due sports, i asked my teachers and friends but they only confused me more.
    thank you for the fast help

    yes the raw data is in x and y x being time and y the difference in temperature as apart of a table we were given.
    what i don't under stand is how do i find A and n in the fist and A and k in the next?? and it dosent pass the x axis when i do it

    This is a double post of this thread.

    See how it clutters the thread?
