====================================
Work Shown:
Plug in x = -5. Use PEMDAS to simplify
f(x) = |3x-2|
f(-5) = |3(-5)-2| ... replace every x with -5
f(-5) = |-15-2|
f(-5) = |-17|
f(-5) = 17
---------------------
Repeat for x = 7
f(x) = |3x-2|
f(7) = |3*7-2| ... replace every x with 7
f(7) = |21-2|
f(7) = |19|
f(7) = 19
