Verified Answer :

The statement,
reflecting the graph of y = cos x across the y-axis is the same as reflecting
it across the x-axis is FALSE. I am hoping that this answer has satisfied your
query and it will be able to help you, and if you would like, feel free to ask
another question.

Answer:

False.

Step-by-step explanation:

The reflecting  graph across y-axis

Rules of reflection :

Along across y-axis if we have a point \((x,y)\rightarrow(-x,y)\)

Along across x-axis if we have a point \((x,y)\rightarrow(x,-y)\)

here, we have y= cos x

So, along x-axis it will become -y=cosx implies y= -cos x

And along y-axis it will become y=cos(-x)=cos x

Hence, both of them are not equal

Therefore, false.
