For a livestock competition, the weight classes for hogs are shown in this table.
Classes:
Light: 200-230 (weight range in lbs.)
Heavy: 230-250 (weight range in lbs.)
a. What is the center of each weight class?
A:
Center of Light class: 215 pounds (lb.)
Center of Heavy class: 240 pounds (lb.)
b. Write functions in terms of y for the range of each weight class. Specify the domain for each.
A:
Light-weight class: y = |x - 215|; 200 \< x \< 230
Heavy-weight class: y = | x - 240|; 230 \< x \< 250
c. Graph the functions on the same coordinate plane for the relevant domain.
A: ?
d. Where would the functions overlap without the domain restrictions?
A: ?

Please! I've been asking for help regarding this question for days.
I think for part C:
match a t chart for x and y
for the light weight, x can be anything bigger than 200 and lower than 230
so x can be 200 all the way to 229
Now do the same for the heavy weight class
then plot them.
for part D:
It's asking at what point the lines intersect
you can set
|x-125|=|x-240|
x=182.5
then plug the x into each equation to find the coordinates for both.
they should be the same.
(182.5, 57.5)
