Write a rule in function notation to describe the transformation that is a reflection across the y-axis.

A. Rx-0(X,Y)
B. Ry-0(X,Y)
C. Ry-x(X,Y)
D. Rx--1(X,Y)

Ry-0(X,Y)

i got on here to get the answer not come look at your questions....

i hate algebra

not sure about your notation, but such a reflection takes (x,y) -> (-x,y)

Nobody cares

well im taking the class as well and i got A

do it urself
