Part A
1. My function represents the relationship between time and the price of gold.
2.This is a function because for every input there is one output.
3. http://www.infomine.com/investment/metal-prices/gold/5-year/
4.The graph represents the relationship between the price of gold and the time in months and years since January 2009.
5. The function is not a linear function.
7. As shown in the graph, the ARC is not constant, and without even
calculate it we can identify it from the shape of the line which
fluctuates over the time period.
8. The function is a mathematical model. because the output is closely related to the value of the input. So for example, the global economic situation the last couple of years have resulted in a drop in the price of gold
Part B
1.http://www.pro-football-reference.com/players/M/MannPe00.htm
2. The relationship between the passing yards of Payton Manning and time is not a function.
3. This relationship is how many passing yards Payton Manning had over his career.
4. It is not a function because P.Manning had the same numbers for passing yards in more than one season, which in our case means that there were more outputs for every input.
Part C
paris,
ReplyDeleteyour explanations for your first graph are accurate. and you chose a good example. it would have been good to show ROC calculations when explaining the linearity of your example. also, you forgot to use function notation, but other than that, good job.
unfortunately, your second example does not qualify as a NON function. if time is input and passing yards are outputs, then the relationship is a function as there are no instances where there are multiple outputs per one input.
