<PRE><B>Question 210294</B>
What does putting a negative sign in front of the equation do?
-------------
If you have y = f(x) and you put a negative infront of f(x),
you get y = -f(x)
------------------------
You have changed the signs of all the y-values.
The graph has flipped over the x-axis.
