Inverse integration?

• Enter the function y(t)=3*t^2-2 for -2<=t< 2 and display the function only.
  
• Create a screenshot of the drawing.
  
• Now display the integral, calculated with an initial t value of -2 and save the integral values to a file.
  
• Open the file, reading in the integral as a new function. Calculate the derivative of this function, using the forward difference method, and create a screenshot of this derivative.

Now answer the following:

1. In what way do the two graphs in the screen shots differ?
   
2. Why are they different?
   
3. Can you change the display setup to replot the graphs so as to be as similar as possible?
