#### Exercise 1.44

Here goes our smoothing function:

Procedure for nth-smoothing:

Note that it we may also think of doing nth-smoothing instead in the following way:

I think it is not correct as this is repeating (smooth f) n times. As to quote from the exercise:

It is sometimes valuable to repeatedly smooth a function (that is, smooth the smoothed function, and so on) to obtained the n-fold smoothed function.

We need to do smoothing of the smoothed function n times.
