pels valors de x inferiors a #x_1, l'expressió és #m_1 (#n_1 #a)
pels valors de x entre #x_1 i #x_2, l'expressió és #m_2 (#n_2 #a)
pels valors de x superiors a #x_2, l'expressió és #m_1 (#n_1 #a)

x	-oo	#x_1		#x_2	+oo
#n	#d3	0	#d4		#d5
#d	#d6		#d7	0	#d8
#e	#s_1	0	#s_2		#s_1

i l'enunciat demana que l'expressió sigui #sig
