Deprecated means the price is decreased, so if something is deprecated by 50% (which just means 1/2 is taken away) its original price is just cut in half. so half of 1200 (1200 divided by 2) is 600. i think the answer is 600 :-)
-2, -5, -8. The pattern shows that the numbers decrease by 3.
It is not a function because it does not pass the vertical line test. For every x value there must be only 1 y value but this graph is not a function because there are 2 y values for every y value.
4, 8, 10, 7, 3, 4... Those r in order from top to bottom! it's all about the simplification!
Wouldn't the answer be 200 if they are going by 2's?
