Find the point on the terminal side of θ = pi divided by four that has an x coordinate of 2.

We are given with an angle of pi divided by 4 and an x coordinate of 2.We can convert pi over 4 from radians to degrees. pi over 4 muliplies by 180 / pi is equal to 45 degrees. The point on the terminal side when x is equal to 2 is represented in the expression tan 45 = y/2 where y is the point. y is equal to 2. The answer is 2. 

Part A-My ordered pairs are 0,3 1,6  2,12  3,24  4,48  5,96  I came up with my order pairs by I used the information that was given which is that the paper starts out flat, with a thickness of 3 millimeters and that the output is the thickness and the input is the number of times folded using this information I came up with first ordered pair 0,3  Zero being the input because it starts out flat meaning it has not been folded and three is the output because in the information it says the thickness is the output, then I came up with my other order pairs by every time it folded the paper doubled the thickness.

Part B- Yes this relation is a function because a function is a special type of relation in which a rule assigns each input with exactly one output and if an input value repeats and is paired with more than one output the relation cannot be a function this being said my order pairs are a function since each input is exactly paired with one output and the inputs dos not repeat, therefore, my relation is a function.
