Answer:
d. x-axis
Step-by-step explanation:
Consider a point on curve P and its (nearest) image on curve P'. The midpoint between those points is on the line of reflection. That line is the x-axis.
_____
<em>Additional comment</em>
The curve is symmetrical about the y-axis, so each point on P also has an image point that is its reflection across the origin. The reflection of P could be across both the x- and y-axes, or (equivalently) across the origin. We don't know the meaning of "xy-axis", so we suspect that is a red herring. The best choice here is "x-axis."
Answer:
Whats the question?
Step-by-step explanation:
Answer:
A. horizontal reflection
Step-by-step explanation:
Given:
To identify the type of transformation.
Solution:
On close observation of the functions we find the that sign of 
has changed in 
with other terms being constant.
<em>Thus, the transformation statement can be given as:</em>
As:
The transformation describes horizontal reflection of function across the y-axis.
Thus, 
is horizontally reflected across y-axis to get .
