Give a response of at least 50 words to the following: Describe the graph of the interval [4, 3).
• Explain how this differs from the graph of the interval [4, 3].
From the question above, does the answer below sound right?
The interval notion is a way to express solutions of an inequality. Points a and b are the endpoints of the interval; we can include parentheses and brackets to express the interval notation. (a,b) shows that the endpoints are not included in the graph, whereas [a,b] shows that the brackets are included in the graph. The graph of the interval [4, 3) includes point 4, but excludes point 3; thus this tells us that 4 is less than or equal to x, and 3 is greater than x whereas [4, 3] is described as a set of all numbers x for which 4 is less than, or equal to x, and 3 is greater than or equal to x…the brackets tell us that the endpoints are included in the graph.

it is ok.

I added a few more sentences, does this sound okay, or should I exclude it?

Thus [4,3] differs from [4,3) because one includes one endpoint[4.3), and the other contains two endpoints [4.3]. This tells us that in the graph the number can be anywhere between 4 and 3, for this interval notation [4, 3], but for this interval notation [4, 3) the numbers can be equal to or less than 4, but any number greater than 3 can be included. 
To me, the second is wordy.

Thanks
