I will give brainelest but i need help on the graph
const2013 [10]

Answer:

1)   (6,2) (9,2) (3,8) (3,5)

2)   (2,-5) (5,-5) (-1,-11) (-1,-8)

Step-by-step explanation:

For the first question, your reflecting over the x-axis into quadrant I, so you just need to make all the coordinates positive.  The numbers stay the same - you just get rid of the negative signs.  (6,2) (9,2) (3,8) (3,5)

For the second problem, you subtract 4 from the x-value, and 3 from the y-value.

(6,-2) becomes (2,-5)

(9,-2) becomes (5,-5)

(3,-8) becomes (-1,-11)

(3,-5)  becomes (-1,-8)

Please Help I will make correct answer BRAINLIEST I PROMISE.......
Mamont248 [21]

Answer:

The correct option is 3.

Step-by-step explanation:

It is given that the length of a rectangle is represented by the function

L(x)=4x

The width of that same rectangle is represented by the function

W(x)=7x^2-4x+2

The area of a rectangle is

A=length \times width

A=L(x) \times W(x)

(L\cdot W)(x)=L(x) \times W(x)

(L\cdot W)(x)=4x\times(7x^2-4x+2)

(L\cdot W)(x)=28x^3-16x^2+8x)

Therefore option 3 is correct.
