This is a follow-up question to Ploting a Piecewise function obtained from linear interpolation of points, where I asked how to construct a piecewise function from a list of points.
I now have two following questions :
1) Is it possible to display the linear interpolation with linear functions $f_i(x) = a x + b$ ?
2) Is it possible to make
h[x_] = Composition[g, g][x] more readable if
g obtained from the previous question --- obviously the plot of
h[x] is correct ?
