Can anyone answer this for me please?

The 2nd and last options.

Step-by-step explanation:

By looking at the table we know that the 2nd one is an answer for sure.

Also by looking at the table we know that the 3rd and 4th are not true.

put in -1/2 in the function to see if you get -2

1/2(-1/2)+3/2

-1/4+3/2

-1/4+6/4

5/4

So The first one doesn't work either.

Now the last one:

1/2(4)+3/2

4/2+3/2

7/2

So the last one works too.

Hope this helps :)

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.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
