Answer:
3 units down
Step-by-step explanation:
Compared to
f(x) = |x|,
f(x) = |x| - 3 moves 3 units down.
Y = mx + c
m = 2/1
m = 2
y = 2x + 3
The coordinates of points in the graph are,
![(-4,-1), (-2,1), (0,-3), (2,3)](https://tex.z-dn.net/?f=%28-4%2C-1%29%2C%20%28-2%2C1%29%2C%20%280%2C-3%29%2C%20%282%2C3%29)
and
![(4,-2)](https://tex.z-dn.net/?f=%284%2C-2%29)
Any other point whose first coordinate(the x-co-ordinate) coincides with one of these points will make the relation not a function.
The relation becomes one- to-many relation which is not a function.
It will also fail the vertical line test , if the points are connected with line segments.
One of such point is,
