To answer this question, let's analyze the provided functions based on their degrees and leading coefficients. We'll match each function to its correct description:

1. [tex]\( f(x)=(-x+1)^3(x+2)^2(x-3) \)[/tex]

- Degree: 6
- Leading Coefficient: -1

2. [tex]\( f(x)=(-2 x+1)^2(x-3)^2(x+1) \)[/tex]

- Degree: 5
- Leading Coefficient: 4

3. [tex]\( f(x)=(x+6)(2 x-3)(x-1)^2 \)[/tex]

- Degree: 4
- Leading Coefficient: 2

4. [tex]\( f(x)=(x-2)^2(-2 x-1)^2(-x+1) \)[/tex]

- Degree: 5
- Leading Coefficient: -4

Now, let's match these functions to the given descriptions.

1. Degree: 4, leading coefficient: positive

The function [tex]\( f(x)=(x+6)(2 x-3)(x-1)^2 \)[/tex] fits this description.
- Degree: 4
- Leading Coefficient: 2 (positive)

2. Degree: 5, leading coefficient: negative

The function [tex]\( f(x)=(x-2)^2(-2 x-1)^2(-x+1) \)[/tex] fits this description.
- Degree: 5
- Leading Coefficient: -4 (negative)

3. Degree: 6, leading coefficient: negative

The function [tex]\( f(x)=(-x+1)^3(x+2)^2(x-3) \)[/tex] fits this description.
- Degree: 6
- Leading Coefficient: -1 (negative)

4. Degree: 5, leading coefficient: positive

The function [tex]\( f(x)=(-2 x+1)^2(x-3)^2(x+1) \)[/tex] fits this description.
- Degree: 5
- Leading Coefficient: 4 (positive)

Thus, we have the following matches:

1. [tex]\( f(x)=(x+6)(2 x-3)(x-1)^2 \)[/tex]: Degree: 4, leading coefficient: positive
2. [tex]\( f(x)=(x-2)^2(-2 x-1)^2(-x+1) \)[/tex]: Degree: 5, leading coefficient: negative
3. [tex]\( f(x)=(-x+1)^3(x+2)^2(x-3) \)[/tex]: Degree: 6, leading coefficient: negative
4. [tex]\( f(x)=(-2 x+1)^2(x-3)^2(x+1) \)[/tex]: Degree: 5, leading coefficient: positive
