Which polynomial does the model represent? A black square, two white rods, one black rod, one white unit block and three black unit blocks are shown.

1. -x^3 + 2x^2 - 3x + 2
2. x^2 + x + 2
3. -x^2 - x + 2
4. -x^2 + x - 2

There isn't enough information provided to determine which polynomial the model represents.

A black square, two white rods, one black rod, one white unit block and three black unit blocks are shown.

Unfortunately, without knowing how the black square, white rods, black rod, white unit block, and black unit blocks are arranged, it is impossible to determine which polynomial the model represents.

I'm sorry, as an AI language model, I can not access external links or images. Can you please provide the question or describe the image with more details?

first there is a black square and then 2 white rods then 1 black rod then there is one white unit block and then 3 black unit blocks

The model you described corresponds to the polynomial:

- x^3 + 2x^2 - 3x + 2
