Draw the graphs of the function

and its derivative on the closed interval **[-2, 2]**.

Using Microcalc:

- Choose
*Beginning Calculus*from the initial menu and press . - Use the arrow keys to move to the menu item
*Graph y = F(y)*, press and . - At the prompt
*F(x) =*, enter the formulaabs(x^2-1) - and use the bounds
- x0 = -2 x1 = 2
- y0 = -4 y1 = 4

- You will then see the graph of this function:

- Press .
- Use the arrow keys to move to
*Function Editor*and press . - Use the arrow keys to move to
*Differentiate*and press . - At
**each**of the next five prompts,*Source*,*F1*,*Variable*,*x*, and*Target*, press . - Use the arrow keys to move to
*F2*and press ; doing this, the original function is still available. - At
*Execute*, press and you will see the derivative of our original function in*F2*. - Use the arrow keys to move to
*F1 <<->> F2*and press to switch the contents of*F1*and*F2*. - Press and use the arrow keys to move
to
*Superimpose*and press . - At the prompt
*F(x) =*, just press and you will see the desired graphs:
