6.4.5. [Smooth] The idea of smoothing a function is an important concept in signal processing. If f is a function and dx is a small number, then the smoothed version of f is the function whose value at a point x is the average of f(x - dx), f(x), and f (x + dx).
Write a function smooth that takes two inputs, a function that computes f and a
$((smooth quad 1) 1)
Step By Step Answers with Explanation
4. Return the inner function as the result of the `smooth` function.
Here's the code in Scheme:
(define (quad x)
(+ (* 2 x) 1))
(display ((smoothed-quad 0))) ; Output: 1
We define the `smooth` function, which takes `f` and `dx` as arguments.
Inside the `smooth` function, we define an inner function that takes a value `x`.
