In mirror reflection transformation from Y-axis, the point co-ordinate that remains same is ____
A
x-value
B
y-value
C
nothing is fixed
D
both are fixed
Explanation: 

Detailed explanation-1: -Since, the reflection is in y-axis, the y-coordinate of the point remains same and x-coordinate changes by sign, i.e. positive becomes negative and vice versa.

Detailed explanation-2: -When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).

Detailed explanation-3: -Answer and Explanation: A transformation that would give the same result as a reflection over the x-axis followed by a reflection over the y-axis is a 180° rotation about the origin.

Detailed explanation-4: -Another transformation that can be applied to a function is a reflection over the x– or y-axis. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis.

Detailed explanation-5: -The y-axis is the vertical axis, so if we were to reflect a function over the y-axis, we would do a horizontal flip. That means that the y-values would stay the same, but the x-values will flip.
