I want to use cumulative frequency curve to draw a box-whisker graph. I have grouped the data and found the location of median, lower and upper quartile, but I don't know how to find the location of minimum because the curve doesn't begin at zero.

If you can find the median and upper and lower quartiles then you should have all the figures included in the cumulative frequency distribution so the minimum is the lowest number and the maximum is the highest input. I think i did pass statistics last semester

first derivative: f ' (x) = 4x - 4x^3 = 4x (1 - x^2) f has minimum or maximum where f ' (x) = 0, i.e. x1 = -1; x2 = 0; x3 = 1 f is of the order of 4 and the term of highest order has coefficient -4, so its graph has two maxima and one minimum. Their coordinates are: maximum 1: x = -1, y = 1 minimum: x = 0, y = 0 maximum 2: x = 1, y = 1 Tangent of the point of maximum 1 is the same as of maximum 2: y = 1 Tangent of the point of the minimum is: y = 0
