Can u help me solve this?
I am trying to do an exponential regression... BY HAND. I realized that I have no idea how to even try. I looked online and couldn't find anything. On my assignment it says to take my first and last data point and find the exponential model by hand.
My data points are (0,68950), (1,57777), (2,40993), (3,29990), (4,23995), (5,19998), (6,12900), (7,9495), (8, 7850), (9,6995) I can graph it on my calculator... but by hand. WHO DOES THAT?! Any help :( |
y = 68950e-0.2668x
I'm not quite sure what you need to do, but I threw the numbers on Excel, and that's the best fit curve. I haven't a clue what kind of class you're taking, but this wiki link will provide some basic info on geometric progressions and links to exponential growth. Edit: Thinking about it some, there may be some iterative method to finding the equation of the curve (if that's what you need to do), but it's been a few years since I've done that stuff. |

Like I said, Excel did it for me;) I want to say I did that stuff in my calculus class, but that was a few years back, and all that information has been muddled now.
