A function is a
relationship that has one output per input. In this article they are talking
about the decline that renewable energy has had after it peaked in 2011. The
years represent the input and the billions of dollars represent the output of
the function. For every year there is exactly a specific amount of billions of
dollars. This function is not a linear function because it does not have a
straight line and the average rate of change is not constant. It is not a mathematical model because the
billions of dollars don’t depend on the year.
Part B:

This graph represents the estimated annual tax breaks for the five biggest companies in the oil industry. It is not a function when the input has more than one output. In this graph the input is the annual tax breaks and the output is ExxonMobil and ConocoPhillips. The input ($600 millions) has two outputs: ExoxnMobil and ConocoPhillips. The input is the taxes because the article focuses on the tax breaks(avoiding tax) big oil companies have annually

ReplyDeleteHey Jean, great job on your examples. The only problem is that in order for part b to not be considered a function barrels of oil has to become the input values and the output values be the years, so each input (barrels of oil) has multiple outputs (Years).
ReplyDeleteThank you Jeffrey I will fix it.
DeleteThe theme that you kept up with in your graphs really helps make understanding these functions easier.
ReplyDeletei Like your graph examples! however, much like Jeffrey said, your second graph isn't appropriate for representing a relation that is not a function.
ReplyDeleteThe graphs you chose are clear and easy to interpret
ReplyDeletejean,
ReplyDeleteyour first example is good. it could have used some more detail in the explanations like showing the ROC calculations to confirm that the graph is not linear, and also, when you were explaining the last part, you forgot to use function notation. other than that good work.
your second example works if you explain it using the dollars as inputs, so good job.
