#piecewise function quick q

Because if you put it where the strictly less than sign is then it would mean to include it in the first function. For instance if you did 0 <= x <= 3 then also have 3 <= x <= 5 on the next line, then you'd have to plot y = x² and y = -4x + 21 for x = 3.
For this they happen to come to the same point (3,12) but for others they might not so it's mainly for having each point in the x axis be part of one equation in the function

ah i see
