You're looking for a (continuous) function that satisfies f (min) = a f (max) = b In your case, a would be 1 and b would be 30, but let's start with something simpler and try to map [min,max] into the range [0,1]. Putting min into a function and getting out 0 could be accomplished with

WebScaling up means that a smaller figure is enlarged to a bigger one. In this case, the scale factor can be calculated by a formula, which is another version of the basic formula given in the previous section. Scale factor = Larger figure dimensions ÷ Smaller figure dimensions The scale factor for scaling up is always greater than 1. WebIf you multiply the random variable by 2, the distance between min (x) and max (x) will be multiplied by 2. Hence you have to scale the y-axis by 1/2. For instance, if you've got a rectangle with x = 6 and y = 4, the area will be x*y = 6*4 = 24. If you multiply your x by 2 and want to keep your area constant, then x*y = 12*y = 24 => y = 24/12 = 2.
