If T: (x, y) → (x - 3, y + 2), then T -1: (x,y) → _____.


A.(x + 3, y + 2)

B.(x + 3, y - 2)

C.(x/3, -y/2)

D.(3x, -2y)

Respuesta :

the correct answer is b (x+3,y-2)

Answer:

B. (x + 3, y - 2)

Step-by-step explanation:

Given,

[tex]T: (x, y)\rightarrow (x - 3, y + 2)[/tex],

Let

[tex]T^{-1}: (x, y)\rightarrow (x+a, y+b)[/tex]

[tex]\implies T^{-1}: (x-3, y+2)\rightarrow (x-3+a, y+2+b)[/tex]

Since, [tex]T^{-1}[/tex] is inverse of [tex]T[/tex]

Thus, by the property of inverse function,

x - 3 + a = x ⇒ a = 3

Also,  y + 2 + b = y ⇒ b = - 2

By substituting the values,

We get,

[tex]T^{-1}: (x, y)\rightarrow (x+3, y-2)[/tex]

Hence, Option B is correct.
