Sagot:
Axis of symmetry# "" -> x = -3 / 2 #
Vertex# "" -> (x, y) -> (- 3 / 2,11 / 2) #
Paliwanag:
Isulat bilang # y = -2 (x ^ 2 + 3x) + 1 #
Isaalang-alang ang 3 mula sa # + 3x #
#color (green) ("Axis of symmetry" -> x _ ("vertex") = (- 1/2) xx (3) = - 3/2) #
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Kapalit # x = -3 / 2 # sa orihinal na equation upang matukoy #y _ ("vertex") #
#color (brown) (y = -2x ^ 2-6x + 1) #
#color (asul) (=> "" y _ ("kaitaasan") = - 2 (-3/2) ^ 2-6 (-3/2) +1) #
#color (blue) (=> "" y _ ("vertex") = - 2 (+9/4) -6 (-3/2) +1) #
#color (berde) (y _ ("kaitaasan") = 11/2) #
