How do you write # f(x) = 4 |x-3|# as piecewise functions? Algebra Linear Inequalities and Absolute Value Graphs of Absolute Value Equations 1 Answer Alan P. Jun 13, 2017 #f(x)={(4x-12color(white)("xxx") if x>= 3),(12-4xcolor(white)("xxx")if x < 3):}# Explanation: If #x >= 3# then #abs(x-3)=x-3# #color(white)("XXX")rArr 4abs(x-3)=4(x-3)=4x-12# If #x < 3# then #abs(x-3) = -(x-3)=3-x# #color(white)("XXX")rArr 4abs(x-3)=4(3-x)=12-4x# Answer link Related questions How do you graph absolute value equations on a coordinate plane?
