Svar:
# Y = 2 (x + 1/2) ^ 2 + 11/2 #
Forklaring:
# "ligningen af en parabola i" farve (blå) "vertex form" # er.
#COLOR (rød) (bar (ul (| farve (hvid) (2/2) farve (sort) (y = a (x-h) ^ 2 + k) farve (hvid) (2/2) |))) #
# "hvor" (h, k) "er koordinaterne til vertexet og en" # "
# "er en multiplikator" #
# "for at få denne formular brug" farve (blå) "fuldføre kvadratet" #
# • "koefficienten for" x ^ 2 "termen skal være 1" #
# RArry = 2 (x ^ 2 + x + 3) #
# • "add / subtract" (1/2 "koefficient for x-termen") ^ 2 "til" #
# X ^ 2 + x #
