what's your function

A:

The relationship I found in this news article was the increase in minimum wage as the years increased. So if this relationship were to be put in mathematical terms, the year would be represented, as the input, and the output would be the minimum wage.

This would be a linear function because as the years pass the rate of the minimum wage rises. (16%-27%)

I could tell that this was a linear function because there was an average rate of change mentioned in the article. There is a function that can be put over an average interval of time( 2014- now) which also proves that this is a linear function

This is a mathematical model because you can see a clear cause and effect in the relationship.
F(y)= W, y=year W=wage. As the Years increase, the Minimum wage increases

B:

The relationship shown in this article shows the temperature in California’s cities within a certain time (7PM 1/16/14). 
The article shows @ 7 PM on 1/16/14
Maryvile, CA 50 F
Mojave, CA 50 F
Livermore, CA 50 F
Napa,CA 50 F




This relationship is not a function because at 7 pm  (time), input, the temperature, output, of certain cities were the same.

  1. Im confused as to how exactly this would not be a function? What is your input and output?

  2. Are you saying that because the 50F repeats this is not a function?

  3. Maybe if the forecast mentioned both a high and a low temperature for the day then the relationship would not be a function.

  4. I think you have a good points about salary wages, however, I couldn't get part B, why you think it's not a function.

  5. Wouldn't it still be a function because the temperatures are in different cities in California, and not just in one?

  6. mai,

    your first example was a very interesting article. it constitutes limited function, one with two data points, but it is still a function. if you are just talking about the increase in wage from 7.25 to 9.32, then yes, it is a linear function.

    your classmates who commented on your second example are all correct in noticing the fact that the example IS a function. if the states are the inputs and 50 degrees is the output, when this function is graphed you will have a horizontal line and that passes the vertical line test.
