Library of Functions – Visualizing Absolute Values
(a)Move the constant function with the mouse or using the arrow keys.
What is the relation between the y-coordinateand the x-coordinateof each intersection point?
The value of g(x) matches the points X coordinate position.
(b)Move the absolute value function up and down either using the mouse
or the arrow keys. In which way does the function’s equation
change?
It adds the value of the Y coordinate (negative or positive) to the
function.
(c)How could this construction be used in order to familiarize students
with the concept of absolute value?
Showing a visual representation of what an absolute value means.
