Correct answers only and you , me the graph shown below expresses a radical function that can be written in the form f(x)=a(x+k)^1/n+c. what does the attached graph tell you about the domain and the range of this function? . a. the domain is [c, ∞) & the range is [-k,∞). b. the domain is [-k,∞) & the range is (-∞,c]. c. the domain is (-∞,∞) & the range is (-∞,∞). d. the domain is (-∞,k] & the range is [c,∞).

A negative number raised to a certain power is equal to an undefined value. In this case, the goal of the have x equal to -k and numbers greater than it. Hence the domain includes k and numbers to infinity. The minimum value of the range is negative infinity up to a value where the first term is zero or range equal to c.Hence the answer is  B. The domain is [-k,∞) & the range is (-∞,c].

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
