I’ll give brainliest (34 points) _(: /」z)_

I am really bad at inequalities, but I can help with 16 for sure!

Remember that a function rule is a formula that you plug an input value into to get your output value

(for example, if you had the correct function rule, you should be able to plug -2 into it and get -4 as a result)

The way we can find said function rule is by finding the right one for the rows that give us both the input and output value (so -2,-4 and 1,-1)

Well, in both of those we can simply subtract 2 from the input value to get the output value. So your function rule is y = x - 2

Note that y = output value, and x = input value.

Using this, you can find your values easily...

They are -5, -3, -2.

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.
