Intersection of two curved lines

    I want to find an intersection between two curved lines. These lines have different values on X-axis but the same values on Y-axis. I attached the values from which the lines are created and also a picture of a plot of these two lines, where the green point is the one Im looking for. I tried some things even from this forum, but nothing seems to work for me.

    Hello,


    If you have already created your Excel chart, you can always add your trendlines to get your equations ...


    1. y = -0.3876x2 + 1.381x + 8.5477

    and

    2. y = -0.3876x2 + 1.7686x + 7.7603


    This is more a math question rather than an excel question ...


    Your intersection point is to be determined with the value of which solves :

    1.381 x + 8.54.77 = 1.7686 x + 7.7603


    Hope this will help
