Which polynomial does the model represent?

a: -x^3 + 2x^2 - 3x + 4
b: x^2 + x -2
c: -x^2 - x + 2
d: -x^2 + x - 2

The model is an algebra tile model.

1st big tile is x², however, it is in black thus it's a negative sign. -x²
2 white tiles represent 2x
3 black tiles represent -3x
3 white small tiles represent + 3
1 black small tile represent -1

-x² + 2x - 3x + 3 - 1 ⇒ -x² - x + 2  Choice C.

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).
