If you flipped the graph y=x^2+2x-2 vertically, you would get the graph y=-(x^2 +2x-2)
true or false

but it was true :(

Hi Astemmene :)

Yes it is true dear.. You are right.

anonymous · Answer

How was that true...?

shayaan_mustafa · Answer

OH wait wait..

I see mistake in my answer. In question it is whole function with -ve sign. So it should be false.

shayaan_mustafa · Answer

@Agent_Sniffles You are right. I have made mistake in seeing the question. Now I look better.

anonymous · Answer

Okay. :P I was getting confused. Haha

shayaan_mustafa · Answer

lol.. :D

shayaan_mustafa · Answer

@Astemmene Answer is false.

accessdenied · Answer

This is true.  If you multiply the value of y by -1, the distance from the x-axis will not change but it will change signs.  If it is positive (above the x-axis) at an x-value, then it becomes negative there.  If it is negative (below the x-axis), then it will become positive.  If it is 0, then it remains unchanged.

shayaan_mustafa · Answer

But whole function is multiplying with - and original is f(x)=x2+2x-2
and g(x)=-f(x)   
i.e.
g(x)=-(x2+2x-2)

shayaan_mustafa · Answer

If it is look like this g(x)=(-x)2+2(-x)-2
then it is of the form g(x)=f(-x) and it is flipped over y-axis. i.e. vertical

So it should be false.

As referenced from Calculus by Howard Anton.

flipping over the y axis is a horizontal flip.  the y-axis itself is vertical:
