Here, you'll find some useful graphs, so that, you can try to study their functions.
But, remember that for a complete study of the function you'll have to wait one more year.
To graph functions, you can use this link (or another one you like better):
INTRODUCTION TO FUNCTIONS
To introduce functions it's very useful to remember some concepts:
To graph functions you can use this link:
But, it´s possible to work with a graphic calculator. There are some of them on line:
MEAN, MEDIAN AND MODE FROM GROUPED FREQUENCIES
The frequency of a particular data value is the
number of times the data value occurs.
A frequency table is constructed by arranging collected data values
in ascending order of magnitude with their corresponding frequencies.
When
the set of data values are spread out, it is difficult
to set up a frequency table for every data value as
there will be too many
rows in the table. So we group the data into class
intervals (or groups) to help us organise, interpret and analyse the
data.
