Oabc is a square o is 0,0 a is -2,2 b is 0,4 c is 2,2 A single transformation of oabc is such that A is mapped to c. C is mapped
Elis [28]

Using translation concepts, it is found that the transformation is a reflection over the y-axis.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For this problem, we have that A is mapped to C and vice-versa. Since they are equidistant to the y-axis, we have that the rule is given by:

(x,y) -> (-x,y).

Meaning that the transformation is a reflection over the y-axis.

For O and B, the rules are given as follows:

  • O: (0,0) -> (-0,0) = (0,0).
  • B: (0,4) -> (-0, 4) = (0,4).

Showing that points O and B are invariant, keeping the same coordinates and confirming that the transformation is a reflection over the y-axis.

Anyone know how to solve inverse of functions ? plz help
Kazeer [188]

In each let y = f(x) and rearrange making x the subject

(7)

y = 3x + 9 ( subtract 9 from both sides )

3x = y - 9 ( divide both sides by 3 )

x = \frac{y-9}{3}

change y back into terms of x

f^{-1}(x) = \frac{x-9}{3}

(8)

y = 5x - 2

5x = y + 2 ( divide both sides by 5 )

x = \frac{y+2}{5}

f^{-1}(x) = \frac{x+2}{5}

(9)

y = - x + 2

x = 2 - y

f^{-1}(x) = 2 - x

(10)

y = - 4x + 3

4x = 3 - y ( divide both sides by 4 )

x = \frac{3-y}{4}

f^{-1}(x) = \frac{3-x}{4}

(11)

y = 0.5x - 2

0.5x = y + 2 ( divide both sides by 0.5 )

x = 2(y + 2)

f^{-1}(x) = 2x + 4

(12)

y = - 0.25x + 6

0.25x = 6 - y ( divide both sides by 0.25 )

x = 4(6 - y )

f^{-1}(x) = 24 - 4x
