The values in the table represent an exponential function. what is the common ratio of the associated geometric sequence? x: 1, 2, 3, 4, 5 y: 22, 38, 54, 70.

is the equation

common difference = 16

Step-by-step explanation:

Given is a table which represent a function.

where dx represents change in x and dy represents change in y.

We see that

Hence x and y have a linear relation with slope 16.

So equation would have the form

Substitute x=1 and y =22, we get

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

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.
