Jawapan:
# (2.5, -0.5) min #
Penjelasan:
# y '= 2 (x-3) * 1 + 2x-4 #
# => 2x-6 + 2x-4 #
# => 4x-10 #
# => 2 (2x-5) #
# y '= 0 #
#=>#
# 2 (2x-5) = 0 #
# => 2x-5 = 0 #
# => 2x = 5 #
# => x = 5/2 = 2.5 #
#y '' = 4> 0 => min #
#y _ ((2.5)) = (2.5-3) ^ 2 + (2.5) ^ 2-4 (2.5) + 3 = #
#=(-0.5)^2+(2.5)^2-10+3#
#=0.25+6.25-7#
#=-0.5#
# (2.5, -0.5) min #
