At which root does the graph of f(x) = (x + 4) 6(x + 7)5 cross the x-axis?
0 -7
ООО

the root for which the graph of cross the x-axis i.e. value of y or f(x) = 0 is  .

Step-by-step explanation:

We have , f(x) = (x + 4) 6(x + 7)5 i.e.. We need to find root for which the graph of cross the x-axis i.e. value of y or f(x) = 0. Let's solve this:

⇒

⇒

⇒

Which means either or , . That means the root for which the graph of cross the x-axis i.e. value of y or f(x) = 0 is or . ∴ From given options , the root for which the graph of cross the x-axis i.e. value of y or f(x) = 0 is  .

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.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
