Question

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

Answer 1

Answer:

A

Step-by-step explanation:

Trust me it is correct. Once you graph it all out it'll make sense

Answer 2

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,∞)
