Input your sample - up to 30 points. Remember that the calculator needs at least 4 points to fit the cubic regression function to your data! The calculator will display the scatter plot of your data and the cubic curve fitted to these points. Below the scatter plot, you will find the cubic regression equation for your data.

To find the equation from a graph: Method 1 (fitting): analyze the curve (by looking at it) in order to determine what type of function it is (rather linear, exponential, logarithmic, periodic etc.) and indicate some values in the table and dCode will find the function which comes closest to these points. Method 2 (interpolation): from a finite number of points, there are formulas allowing to ...

If he reduces each side by 1 unit, the volume shrinks to 12. Find a function f(x) that gives the volume of the box when the sides are increased by x units. The four data points are (0, 40), (1, 90), (2, 168), and (-1, 12). Plugging these values into the calculator or matrix equation gives us a = 1, b = 11, c = 38, and d = 40.
