Which polynomial does the model represent?

The model shows 1 black square block, 2 white thin blocks, 1 black thin block, 1 white small square block, 3 black small blocks.

a –x³ + 2x² – 3x + 2
b. x² + x – 2
c. –x² – x + 2
d. –x² + x – 2

Is it a

pls help steve

pls help me steve

i think its a or d

is anon right?

To determine which polynomial the model represents, we need to analyze the pattern of the blocks and compare it to the given options.

Let's break down the given options and analyze each polynomial:

a) –x³ + 2x² – 3x + 2
b) x² + x – 2
c) –x² – x + 2
d) –x² + x – 2

Now, let's analyze the model:

The model shows:
1 black square block
2 white thin blocks
1 black thin block
1 white small square block
3 black small blocks

We can represent each block type with a letter:
- Black square block (B)
- White thin block (W)
- Black thin block (b)
- White small square block (w)
- Black small block (b)

Putting the pattern in order, we get: BWWbwbbbb

Now let's analyze each given polynomial to find the pattern that matches the model:

a) –x³ + 2x² – 3x + 2
In this polynomial, the exponents and coefficients do not match the pattern of the model. It cannot represent the given sequence.

b) x² + x – 2
This polynomial includes only terms with powers of x and no constant term. It does not match the pattern of the model. It cannot represent the given sequence.

c) –x² – x + 2
In this polynomial, the exponents and coefficients do not match the pattern of the model. It cannot represent the given sequence.

d) –x² + x – 2
This polynomial includes terms with powers of x and a constant term. The pattern of the terms matches the pattern of the model. It can represent the given sequence.

Therefore, the correct polynomial that represents the model is option d:

d) –x² + x – 2

C, D, C, B, B, D, C, A, B, A, D, D, C, A, D, D, C, A, A, B, A!
