What's your Function?-Rae'ven

Dangerous Toys 

The article, Dangerous Toys, discussed the dangers of motorcycles, riding all-terrain vehicles (ATV) and two-wheeled motorbikes (MB) which cause significant injury to children. The study’s within the article’s aim was to quantify the burden of motorcycle trauma presenting to Starship Children’s Hospital by assessing the annual admission rates, severity and pattern of injuries, and patient mortality, and to compare injury patterns of those riding all-terrain vehicles (ATV) and two-wheeled motorbikes (MB). Their conclusion was that motorcycle trauma was increasing. 

1. This function represents the number of patients admitted to the Starship Children's Hospital for ATV, Motorbike, and both ATV and motorbikes in the years 1999 through 2008. I know this is a function because the functions have exactly one output paired with exactly one input. The lines also  pass the vertical line test.

2. This relationship is not a linear function because the function is not a straight line and it does not have a constant rate of change at every interval. 

3. The function is not a mathematical model because the function's outputs, number of patients, does not depend on its inputs, year. Function notation: No. of patients = f (year)


Part b:Acquired 'theory of mind' impairments following stroke  
The article, Acquired 'theory of mind' impairments following stroke, discusses `theory of mind'. The article reports a study that examined theory of mind in adults who had suffered right hemisphere stroke, a group known to show pragmatic and social difficulties. In one study, shown above in the Scatter Plot, using cartoons, patients' understanding of materials requiring attribution of mental states (e.g. ignorance, false belief) was significantly worse than their understanding of non-mental control materials. Data from healthy elderly subjects, and a small group of left hemisphere patients, suggest that this impairment on mental state tasks is not a function of task difficulty. 

1. The scatter plot represents the study of 12 single-frame cartoons taken from popular magazines. One theory of mind (ToM) cartoons, in which the humor depended upon what a character mistakenly thought or did not know, and non-mental cartoons in which the humor did not involve a character's false belief or ignorance but instead involved a physical anomaly or violation of a social norm. The darker dots represent the control group, which consisted of 19 healthy elderly individuals, while the lighter dots represent the RHD, right hemisphere damaged group. The individual explanation scores on the y axis represents the participants' answer to the experimenter's question of why each cartoon was funny. 

2. I know this relationship is not a function because it does not pass the vertical line test nor is there only exactly one output paired with exactly one input. Also, in this relationship for Single cartoons: Non-metal, one input is paired with two outputs.

  1. Rae'ven,
    Great choice in articles! I really lied how you explained your information in great detail, which allowed me to process and learn from what you wrote about!

  4. Rae'ven,
    I think it is interesting that for you second graph, there is a control group. Not too typical considering the graphs everyone else has posted.

  5. rae'ven,

    great job on your first example! your explanations are well done and in good detail!

    at first glance, it does look like your scatter plot for the second example is not a function, but upon detailed examination, you can see that it DOES pass the vertical line test and there are no repeated input values.

    other than that, good job.
