The line which you folded is called the line of symmetry. This divides the parabola into two matching halves or mirror images. The equation of the line is x = ___ because it is vertical. Look to see where your folded line crosses the x-axis. Choose the equation below.
A. x = -2
B. x = 2
C. x = 0
D. None of the above

what is the equation of the parabola? Is it given?

anonymous · Answer

yes leyla, look to ensure you did not leave out any information.  in order to determine the line of symmetry we need to know more information

x = -b/2a  is the formula for finding such a line

anonymous · Answer

no thats the hole question they have

mani_jha · Answer

The question says, "Look to see where the folded line crosses the x-axis". You must be having some diagram or graph with that question
