Forms of Quadratic equations
Please help me out

Standard form:

1. y = x² - 4x - 5

2. y = x² - 2x - 8

3. y = x² + 4x - 21

4. y = x² + 12x + 20

5. y = x² + 8x + 12

6. y = x² + 4x + 3

7. y = x² - 8x + 7

8. y = x² - 6x + 8

9. y = x² + 10x - 11

Vertex form:

1.

2.

3.

4.

5.

6.

7.

8.

9.

Factored form

1. (x + 1) (x - 5)

2. (x + 2) (x - 4)

3. (x - 3) (x + 7)

4. (x + 10) (x + 2)

5. (x + 6) (x + 2)

6. (x + 3) (x + 1)

7. (x - 7) (x - 1)

8. (x - 2) (x - 4)

9. (x + 11) (x - 1)

NB: I am skipping the vertex form since I haven't heard of it before.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
