I have equation of 3 different curves and now i have to plot graph of those curves in a single plot graph and get intersection. how can i do that ? basically i wanted to do dynamic time warping equations of the curves are 1-2.481*10^(-7)x^4 - 4.93*10^(-3)x^3 + 0.002619x^2 + 0.01026x + .2813 2-2.258*10^(-7)x^4 - 4.407*10^(-3)x^3 + 0.002397x^2 + 0.006693x + .6821 3-1.298*10^(-6)x^4 - 0.0001621x^3 + 0.006248x^2 - 0.01043x + 1.021
