you plot without the modulus sign first
then you reflect the -ve portion about the x-axis, and change it
to positive
Reasoning: -1 becomes 1, and -2 becomes 2
so if the original turning point was at (x, -2), after modulus, it
will become (x, 2)
In short, just reflect everything under the x-axis to above the
x-axis, and keep everything above the x-axis the same
Eh, as in for the points used, do i do all the values ranging from
-1 to 5??? or i can skip a few of the values? this is the table
plotting style... otherwise, i have to use the when y=0,
x=___, format.
