Problem:
Using MPP, graph the following function

Visualization:
  1. Choose Item 1 - MPP (Mathematics Plotting Program) from the initial menu and press .
  2. Enter the bounds
    Xmin : -4 Xmax : 4
    Ymin : -4 Ymax : 4 .
  3. At the prompt 1. y=f(x) ==>, enter the function
    -3 - x
    and enter the bounds
    xmin : -4 xmax : -2
    .
  4. At the prompt 2. y=f(x) ==>, enter the function
    2x
    and enter the bounds
    xmin : -2 xmax : 2
    .
  5. At the prompt 3. y=f(x) ==>, enter the function
    x^2 -4x +3
    and enter the bounds
    xmin : 2 xmax : 4
    .
  6. Press to display the graphs of the functions.
