Svar:
# "Spidsformen er:" y = 1/2 (x + 3/2) ^ 2-41 / 8 #
Forklaring:
# "Spidsformen dannes som y =" a (x-h) ^ 2 + k #
# "Hvor (h, k) er vertex-koordinater" # #
# "Vi skal omarrangere den givne ligning." #
# Y = 1 / 2x ^ 2 + 3 / 2x-4 #
# Y = 1 / 2x ^ 2 + 3 / 2xcolor (rød) (+ 9 / 8-9 / 8) -4 #
# Y = 1/2 (farve (grøn) (x ^ 2 + 3x + 9/4)) - 9 / 8-4 #
#COLOR (grøn) (x ^ 2 + 3x + 9/4) = (x + 3/2) ^ 2 #
# Y = 1/2 (x + 3/2) ^ 2-41 / 8 #
