graphing calculator
It takes many weeks of training to learn how to use the graphics calculator and the methods demonstrated here are not the only ones. We only have time for some basic familiarisation.
Part A:
Use table mode to draw the following graphs. Four graphs are positive (upright or happy) and two graphs are negative (upside down or sad). You will need to learn when to click the EXE key (it is like the = key on normal calculators and follows most actions. Use the EXIT button when you get lost to take you back to a previous menu. Refer to the screenshots if you get stuck.
You can delete a graph once you have graphed it but you can store all six graphs and simply 'select' the one you want to draw. The calculator cannot solve graphs if two or more are drawn on the screen.

Part B:
Use Graphing mode to locate and label the coordinates of the vertices (minimum and maximum points), the y axis and x axis crossing points.

example
Use table mode to draw the following graph:
Use graphing mode to locate important information about the graph like x and y crossing points and minimum and maximum points. Use the same functions as above.
These are the essentials for graphing functions like parabolas. The calculator is much more powerful than this and it takes many weeks to really become familiar with its use. Ideally you would use both the calculator and drawing methods from a table. You have to decide if the investment is worth it. Your teachers in the following years will advise you on what to do. Most teachers have class sets. However, there are never enough for everyone.
