Ineed to calculate for *g(-1*)- the option are; is greater, equal or less than h(-1) and then for *g(1)*- the option are; is greater, equal or less than h(-1)

From the graph, we can see that when , then . On the other hand, we need to calculate , that is, the output of at , so . Well, we have two values:

For the options are:

a) is greater than

b) is equal than

c) is less than

Since:

The correct option is:

c) is less than

From the graph, we can see that when , then . From the previous exercise, we know . So we have:

For the options are:

a) is greater than

b) is equal than

c) is less than

Since:

The correct option is:

c) is less than

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.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
