Domain and Range Objective: Know the difference between Domain and Range, and know how to find them to determine if a relation is a function.  Example: Find the Domain and Range of the following Relation and determine if it is a function: {(-3,5),(-2,5),(-1,5),(0,5),(1,5),(2,5)}                   Domain (x-values): {-3,-2,-1,0,1,2}                   Range (y-values): {5} Is this relation a function? Yes,  the relation is a function because none of the x-values repeat. Analysis Misconceptions: One misconception I had was that I did not know what "|" was in inequality notation like {x|x>4}. I overcame this by asking the teacher what this meant, and it means "Such that". So in the example it would mean {x such that x is less than four} Essential Question 1: How do you find the Domain and Range? Answer: Domain and Range is just the x- and y-values, so by find...

The top graph was the easiest conjecture to make. The x-value assymptote increases or decreases,  Both graphs were hard to make a conjecture about, as they are pretty equal, One reflects it across the x-axis, while the other reflects it across the Y-axis. The top one either makes it go infinitely positive on the Y-value, and infinitely negative on the x-value or makes it go infinitely negative on the y-value and infinitely positive on the x-value.  Misconceptions? I really didn't have any misconceptions while working on this investigation as I had a pretty good understanding on the basics of translating a table to a graph, and then being able to read the graph.
