Just plug in your equation and it appears on the grid and you will notice the roots obviously on x-axis

phi · Answer

I would take time to learn how to do this with your calculator
some tests expect you to know how to use the calculator, (not a computer)

triciaal · Answer

@phi  can you please outline the steps to use a graphing calculator

@triciaal Are you looking for instructions to plot on a TI 83 family of calculators?
I work with a TI-83, but higher families are similar.
If so, here's what you do:
1. turn on the calculator (bottom left button)
2. Clear (if necessary)
3. Press "y=" button (top left)
4. Enter the function on the first y= line.  Press enter (bottom-right)
5. Press "window"  (to the right of "y=")
6. adjust the size of the window (for this function, you could try the following settings:
- xmin=-5
- xmax=5
- ymin=-1000
- ymax=1000
- xscl=1 (default)
- yscl=1 (default)
- Xres=1
7. Press "graph" (top right)
It may take 2 seconds to show the graph, but it should display the graph of the given function.
