Part
a:
2. A relationship is considered a
function when there is exactly one output paired with exactly one input and if
it passes the vertical line test.
3. A relationship in this periodical
was the increase in amount of stores that Michael Kors opened and their
quarterly earnings. In 2011 there were 231 stores and in 2014 there were 703
stores.
4. This relationship shows a general
negative correlation because as the amount of open stores is increasing, the
quarterly earnings are slightly decreasing.
5. No this is not a linear function.
6. N/A
7. The average rate of change does
not stay constant.
8. This is not a mathematical model
because the growth or decline of earnings is not a function of the quarter of
fiscal growth.
Part
b:
1. A relationship is not a function
if there are multiple inputs per single output and if it does not pass the
vertical line test.
3. This relationship is explaining
the amount of measles cases each year since 2001.
4. This relationship is not a
function because the graph shows that there are multiple outputs for
This is cool research on the Michael Kors stores opening and quarterly earnings decreasing -- I would think that more stores would cause the earnings to increase. Interesting relationship!
ReplyDeleteThis is a good analysis of the function, but I think if have graphs will be better! Good job.
ReplyDeleteI like the choices of measles and Michael Kors! also, I agree with Channing and thought that they would only open more stores if they were doing better. Good job Blake!
ReplyDeleteIsn't the relationship between measles cases and years considered a function? For each input (year), there is only one output (number of reported measles cases). Just because the information is presented as a bar graph doesn't mean that the relationship is not a function... What are your thoughts?
ReplyDeletebrenna,
Deleteyou are absolutely correct!

blake,
ReplyDeleteyour first example is well done, an interesting article, and explained well.
your second example, unfortunately, is not an example of a non-function. there is one output per input, even if the way the information is presented makes it appear like there are multiple outputs per input.
other than than, overall good job.
