Quadrilateral ABCD is graphed on a coordinate plane with the vertices A(-9,6), 3(-4,-6), C(-3,2), and D(-3,-2)
MrRissso [65]

A. The translation rule is (x , y) → (x - 2 , y + 6)

B. The coordinates of the vertices of the image are A' (-11 , 12) , B' (-6 , 0) , C' (-5 , 8) , D' (-5 , 4)

Step-by-step explanation:

Let us revise the translation of a point

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units then its image is (x , y - k)

A.

∵ Quadrilateral ABCD is translated to the left 2 units and up 6 units

- That means subtract 2 from each x-coordinates and add 6

  to each y-coordinates

∵ (x , y) is moved to the left 2 units ad up 6 units

∴ Its image is (x - 2 , y + 6)

The translation rule is (x , y) → (x - 2 , y + 6)

B.

∵ The vertices of the quadrilateral ABCD are

A (-9 , 6) , B (-4 , -6) , C (-3 , 2) , D (-3 , -2)

∵ Quadrilateral ABCD is translated to the left 2 units and up 6 units

- Use the rule in part A to find the image of each vertex

∵ A' = (-9 - 2 , 6 + 6)

∴ A' = (-11 , 12)

∵ B' = (-4 - 2 , -6 + 6)

∴ B' = (-6 , 0)

∵ C' = (-3 - 2 , 2 + 6)

∴ C' = (-5 , 8)

∵ D' = (-3 - 2 , -2 + 6)

∴ D' = (-5 , 4)

The coordinates of the vertices of the image are A' (-11 , 12) , B' (-6 , 0) , C' (-5 , 8) , D' (-5 , 4)

NEED HELP NOW!!!!
Dovator [93]

Answer:

f(x) = -3x --->#6

f(x) = |x-1|+3 --->#5

f(x) = √(x+3) --->#3

1/2x² --->#1

f(x) = (x+1)²-3 --->#4

4|x|--->#2

Step-by-step explanation:

Recall for transformations:

  • Adding a number outside the function moves it up
  • Subtracting a number outside the function moves it down
  • Adding inside the function moves it to the left
  • Subtracting inside the function moves it to the right
  • Multiplying to the function by a number less than 1 compresses
  • Multiplying to a function by a number greater than 1 stretched it
  • Multiplying by a negative flips the graph

f(x) = -3x

This is multiplication by a number greater than 1 and a negative so this stretches and flip. This is #6, a reflection.

f(x) = |x-1|+3

Subtraction inside the function shifts it to the right 1 and addition outside shifts it up 3. This is #5.

f(x) = √(x+3)

Addition inside the function shifts it to the left 3. This is #3

1/2x²

Multiplication by 1/2 which is less than 1 compresses it. This is #1.

f(x) = (x+1)²-3

Addition inside the function shifts the function to the left once. This is #4.

4|x|

Multiplying by 4, a number greater than 1, stretches it. This is #2.
