The model that describes how data is written to a blockchain is the: append-only data structure.
<h3>What is an Append-only Data Structure?</h3>
Append-only is computer data storage property whereby new data can be added to a blockchain, like an additional block, in a time-ordered sequential order in such a way that the data added cannot be easily altered as al data are permanently stored across all nodes.
The append-only data structure makes data stored almost immutable. This is the model in which the blockchain technology is built on.
Therefore, the model that describes how data is written to a blockchain is the: append-only data structure.

Answer:
Explanation:
Part D
For d, the very first thing you need to do is figure out which one of the steps you are going to use. You have 2 in b^2 + 2, so even if b = 0 the two still matters. It means that you use f(x) = -x + 3 because that's what you use when you have 2 or above.
The second thing you have to realize is that f(x) = -x + 3 has the meaning of what ever you see on the left in the place of x, you put on the right wherever there is an x.
In this case f(b^2 + 2) = -b^2 - 2 + 3 = 1 - b^2
