The image of a parabolic mirror is sketched on a graph. The image can be represented using the function y=-3x2 + 2, where x represents the horizontal distance from the maximum depth of the mirror and y represents the depth of the
mirror as measured from the x-axis. How far away from the maximum depth is a point on the mirror that is inches
in depth?
O 3 inches
4 inches
5 inches
6 inches

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

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.
