Answer:
C. 32/3 or 10 2/3
Step-by-step explanation:
I think this is the right answer...
The correct statements regarding the behavior of a quadratic function are:
- The function in increasing for all real values of x where -6 < x < -2.
- The function is decreasing for all real values of x where x < -6 or x > -2.
<h3>When is a quadratic function increasing or decreasing?</h3>
A quadratic function with roots and is defined by:
In which a is the leading coefficient.
The coefficient influences the behavior, as follows:
- If a < 0, the function is increasing between the roots, and decreasing otherwise.
- If a > 0, the function is decreasing between the roots, and increasing otherwise.
In this problem, the function is:
f(x) = -(x + 6)(x + 2).
The roots are x = -6 and x = -2, and the leading coefficient is of a = -1 < 0, hence:
- The function in increasing for all real values of x where -6 < x < -2.
- The function is decreasing for all real values of x where x < -6 or x > -2.

1. Multiply x and 3y by x-2
x^2-2x (i.e. x*x=x^2, -2*x=-2x)
3yx-6y (i.e. 3y*x=3yx, 3y*2=6y)
2. Multiply x+y by -4
x*-4= -4x
y*-4=-4y
3. Multiply 2x+3y by -1
2x*-1=-2x
3y*-1=-3y
4. Combine like terms
x^2 3yx -2x -6y
-2x -3y
-4x -4y
-------------------------------------------
x^2 +3yx -8x -13y
