To be able to graph most application questions, you need to learn how to change the table set and the window of your graph. Most things hit the ground within seconds... So you don't need to look at any negative numbers and you won't need to have the x-axis go up to 10.
Table Set: This adjust the x input numbers. Things go up and fall down fast. You will often need tenths of a second to look at.
Hit the following keys on your calculator.
"Window button" It says table set above it
This will give you the height for every tenth of a second.
Window (What you see when it is graphed) Many things go up much higher than 10. This will allow you to see what the parabola looks like.
Hit the following keys on your calculator.
Xmin = 0 Nothing happens before 0 time.
Xmax = 5? 3? 10? Since this represents time, it won't be too high.
Xscl = 0.1 (This will allow every tenth of a second to show) - If you don't need tenths, keep it at one.
Ymax = ??? (This is hard to say. If it is a cannon or a tall building, then you need to figure out how high this parabola is going to go. If it is a flea jumping... well you don't need the y-axis to go very high.)
Yscl = ??? (If you are graphing up to 200, you only need to see a little hash mark every 50. You again need to decide based on the question.)
You will need to see what equation you are using and need to adjust. You may cut off the top of the parabola, then you need to make the Ymax higher. You may need to see only up to 3 seconds, you change the Xmax.
Below are two videos to help with this if you need more assisstance.
