pointed bracket or singular function

y = -5*x^3 + 180*<x-1>^2 - 10/12 * <x-2>^4 + 10/12*<x-4>^4 - 10*<x-5>^3 - 535*x

is there anyway to input this formula into the HP Prime where the terms in < > will drop out if they evaluation less than zero????

You can use the MAX (maximum) function (Math menu, Arithmetic) and type (for example) MAX(0,x-1).
