Part A
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.

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
ReplyDeletegiovanni,
ReplyDeletehelene 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.
