The
domain of
the absolute value function is the set of all real numbers. The
range
is the set of all real numbers greater than or equal to zero.
It is an even function and is
decreasing
on the interval from negative infinity to zero, and
increasing
on the interval from zero to positive infinity.
The graph intersects
the x-axis and y-axis at (0,0).
Important
anchor point
coordinates are:
(-1,1) (0,0) and (1,1).
You can graph many variations of the absolute value function using
transformations. Check out examples of
vertical stretch and
vertical compression.
