sorry, here is the question Observe that maintaining the same x0 inputs for the scramble_image and unscramble_image functions but varying the input for only one of them - from = 2 to = 1.999999 say - has the same effect as above. This means that the 'key space' for the cypher has two dimensions and is potentially very large, depending on the precision used to store and compute with floating-point numbers. Comment on what happens to this key space when the tent map is replaced with the map f(x) = x
