Blog post 2
Part A
1.)
The graph above shows a function in an article about how the human population has increased over time. It is a function because it passes the vertical line test and every input has an output. It is not a linear function because there is no constant rate of change considering population increases more rapidly as time goes on. It isn’t a mathematical model since the outputs aren’t dependent on the inputs or in function notation, Q isn't’t dependent on t.


Part B


1.)    The article I found discusses how education correlates to unemployment rate; however, neither column represents a function because if graphed both will fail the vertical line test. Instead of being a function, this table just compares the unemployment rate to those with less than high school education and those who have a college education or more.

  1. I think the second graph actually does show a function but because of the scale of the graph there is a very limited possibility of observing these changes so suddenly

  2. giovanni,

    helene is correct. both representations show relationships that are functions. also, i think you may have switched the graph and table for part a and b. you are correct in your explanations about the graph. but for the table, there are no repeated input values, so it is a function.
