    Unhappy Exponential Equations

    I'm having difficulty writing this out as an exponential regression equation, any help?

    Can't you input the data into appropriate software or technology and get an answer?

    I have except this doesn't look right to me.

    15195.93133*1.046264335^x

    and even if it is, I have a extremely difficult time figuring our window settings any tips?

    And sorry for bumping the topic, I simply really need help. I have no idea what i'm doing and I have an exam on this tomorrow

    i think your equation is okay. as far as window settings go, just make xmax = max time, so here xmin = 0 and xmax = 5

    and make ymin something that looks plausible. if it goes 16000 to 16500 to 17400, you're probably safe with 14000 as ymin, and obviously ymax would be around 19100.

    And what about the scale?

    I really need to know the scale, i've tried multiple combinations and it its showing me is a slant pointing upwards, meaning that I need to make the window bigger so I can see the shape so I can do the questions that come with it.

    Any help?
    Because of the numbers involved you will struggle to produce a graph that look like an exponential graph (that is, curving upwards). Your graph will look like a line -but the curve is there. The suggested window settings are reasonable to use.
