Homework Help: Solving for Minimum point Excel

  1. May 9, 2017 #1
    1. The problem statement, all variables and given/known data

    Hello, I trying to solve for the minimum value that the x and y components reach in plot (A). I know that you can perform this using IgorPro but I would like to know how to solve for it using Excel.


    The plot was constructed using the following data points:

    110 0.177
    115 0.093
    120 0.033
    125 0.006
    130 0.007
    135 0.04
    140 0.101
    145 0.186
    150 0.272

    As you can see there is a minimum x and y data point. However, I want to solve for the minimum point that the polynomial fit reaches.
    2. Relevant equations

    3. The attempt at a solution

    Or, if you don't know calculus, you can just complete the square on your polynomial to figure out the minimum.
    [Edit, added] The graph you show is not the correct graph for the polynomial you gave.
