hey everyone, i have a question, by looking at a particular graph, how will you estimate the amount that is asked in a problem? (e.i. revenue, profit, stocks, etc) Do you just guess or something?
First we have to read the title of the graph, i.e. what kind of information the graph conveys, it could be the profit of a company over different years, etc.
Next you have to identify what the axes represent:
the x-axis (the one that goes from left to right) usually represent a variable that progresses regularly, such as time, year, etc.
the y-axis (the one that goes from bottom to top) represents the profit, loss, etc. i.e. values corresponding to the year, etc.
From the graph, you can determine if the profit has increased (get higher to the right) or decreased, etc.
For more detailed information, and possibly some U-tube videos, you can try the following link and make your own selection of description or presentations:
