**how to find the equation of a cubic function? Yahoo Answers**

This is a cubic equation in h 2, with known coefficients, since we know e, f, and g. We can use the solution for cubic equations shown above to find a positive real value of h 2 , whose existence is guaranteed by Descartes' Rule of Signs, and then take its positive square root.... t = linspace(1,5,100) Finding the cubic spline using the function: splineX = spline(x,y,t); I have used the command to be able to plot function splineXbut I'm not sure how I can find the actual equation the spline function calculates (I know that for this data it would simply be a straight line but

Explanation This question requires an understanding of cubic functions as well as how to find the intersection of two curves. This can be used to make an equation for the intersection points from which the maximum number of intersections can be found....The calculator will find the roots of the cubic equation in both the analytic and the approximate forms. Show Instructions In general, you can skip the multiplication sign, so `5x` is equivalent to `5*x`.
