write a function that starts at 20 and triples every 7
I'm sure you have just learnt about exponential functions!
Utilize that knowledge to find a solution to your problem.
Hello jared89, welcome to the forum
You could use the exponential function in a general form and start fitting it to the two conditions you have, however there is a slightly more advanced way. Write out the two conditions as:
Take the derivative of the second one and use in it the original again. You will end up with a first order differential equation giving as solution the exponential function. Using the first equation as boundary gives then the function you are looking for.
Can you do this?
