What is the effect on the graph of f(x) = x2 when it is transformed to h(x) = 2x2 – 9?
-
A. The graph of f(x) is vertically compressed by a factor of 6 and
shifted 9 units to the right.
B. The graph of f(x) is horizontally compressed by a factor of 6 and
shifted 9 units down.
C. The graph of f(x) is vertically compressed by a factor of 6 and
shifted 9 units down.
D. The graph of f(x) is horizontally stretched by a factor of 6 and
shifted 9 units to the right.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

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.

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
