What is the vertex and axis of symmetry?
2 answers:
Check the picture below.
now, the Range and Domain are both assuming the lines goes no further, keeping in mind that most lines go to infinity.
the x-intercepts are just where the graph intersects or touches the x-axis.
the y-intercepts are just where the graph intersects or touches the y-axis.
vertex is simply where it makes the U-turn, and <u>axis of symmetry</u> is simply most of the time the x-coordinate of the vertex, of namely <u>the line where the graph begins making a mirror image</u>.

2012 - 2014 = -20%
2012 - 2013 = +20%
2013 - 2012 = 1 = 100%
Soo :
100% - 20%
= 80% (E.)
