Write a function rule using function notation that will transform a geometric figure by rotating it 270 degrees clockwise. a f(x, y)=(-y, x) b f(x, y)=(y, x) c f(x, y)=(-x, y) d f(x, y)=(x, -y)

Respuesta :

Answer:

a

Step-by-step explanation:

Under a clockwise rotation about the origin of 270°

a point (x, y ) → (- y, x ) , thus

f(x, y ) = (- y, x )

Given:

Function 'f' with two variables 'x' and 'y'.

To find:

Function rule if the parent function 'f' is rotated by 270° clockwise.

Solution:

A function given with two variables 'x' and 'y',

f(x, y) → (x, y)

If this function is rotated by 270° clockwise, the function rule will become,

f(x, y) → (-y, x)

Therefore, Option A will be the correct option.
