which polynomial does the model represent (Model shows: 1 big black square, 2 long blank rectangles, 3 long rectangles, 3 small blank squares, 1 small blank square)

Question

a.) -x^3+2x^2-3x+2
b.)x^2+x-2
c.)-x^2-x+2
d.)-x^2+x-2

Answer 1

The description seems a bit unclear; however, we will try to associate each shape with a term of a polynomial.

1 big black square = -x^2
2 long blank rectangles = +2x
3 long rectangles = -3x
3 small blank squares = some discrepancy, as there's no 3 or -3 constant term in any option, could be a typo in the model.
1 small blank square = +1

Combining these, we get -x^2 +2x -3x +1 or -x^2 -x +1, but none of the options match exactly. The closest one is option c.) -x^2 -x +2 which might represent the model with a typo or misinterpretation.
