Question

What are the domain and range of the parent function of an absolute value equation?
A.
domain: all real numbers, range: all real numbers
B.
domain: all real numbers, range: all real numbers greater than or equal to zero
C.
domain: all real numbers greater than or equal to zero, range: all real numbers greater than or equal to zero
D.
domain: all real numbers greater than or equal to zero, range: all real numbers

Answer 1

y=|x|
The domain can be all real numbers because of this. But the range is all greater or equal to than zero. Domain: x values, range: y values.
So let's start with like -5.
y=|-5|
Absolute value turns the number into a positive.
y=5
The lowest y can be is 0.
y=|0|
0=|0|
It would look like this:
