Graph the function y = |1.6x - 2| - 3.2. Over which interval is the function increasing?

Hmm,

the absolute value makes whaterver inside positive

so

find whre the abslte value is 0

1.6x-2=0

1.6x=2

x=2/1.6

x=1.25

as x approaches 1.25, the function decreases

so from left to right

from the left to right, from - ifninty to 1.25, it is decreasing

from 1.25 to infinity, it is increasing

so it is increasing in the interval (1.25,∞)
