How to find the global equation of a dual curve?

How do you find the equation of the curve of best fit!?

  • Answer:

    First, you plot the points on a graph. Next, you draw a line of best fit, which is a line that is closest to all points. Finally, you get the x-intercepts(where the line intersects the x-axis). After that, you can create a equation (x-[intercept1])*(x-[intercept2]). Multiply that out that quadratic, and you have your equation.
