a study designed to determine if there is an association between an adverse effect in a large population and exposure to a particular agent is an Epidemiological study.
Epidemiology is the observation of the distribution of diseases and other fitness-related situations in populations, and the utility of this study is to manipulate fitness issues. The time period epidemiology is now broadly carried out to cover the description and causation of not the most effective epidemic, infectious ailment, but of sickness in preferred, along with associated situations. some examples of topics examined via epidemiology consist of excessive blood stress, mental illness, and weight problems. Saving Lives. shielding human beings. Saving cash via Prevention. Epidemiology is the examination of the starting place and reasons for diseases in a network.
Cohort studies are fine for analyzing the herbal progression of ailment or chance elements for sickness; case-manipulate studies are lots quicker and less pricey. Qualitative research methods are a key component of discipline epidemiologic investigations due to the fact they are able to offer insight into the perceptions, values, critiques, and community norms in which investigations are being carried out (1,2).

There is a Y axis and a X axis on the graph, they can be our equation. If the plot is (1,3) then, X=1 and Y=3, you can assume that it's X = 3. If the plot is (2,4), then X = 2, Y = 4, just divide/ simplify both sides my 2, and X = 2.
Make x the subject means you need to solve for x
y = ax^2 solve for x
divide both side by a
y/a = ax^2/a
simplify
y/a = x^2
so
x = square root (y/a)
The answer is exponential decay
