Sagot:
Ang form ng Vertex ng equation ay #y = -25 (x-0.16) ^ 2-12.36 #
Paliwanag:
#y = -25 x ^ 2 + 8 x -13 # o
#y = -25 (x ^ 2-8 / 25 x) -13 # o
#y = -25 {x ^ 2-8 / 25 x + (4/25) ^ 2} +25 * 16/625 -13 # o
#y = -25 (x-4/25) ^ 2 + 16/25 -13 # o
#y = -25 (x-4/25) ^ 2-309 / 25 # o
#y = -25 (x-0.16) ^ 2-12.36:. # Nasa Vertex
#(0.16, -12.36)# at vertex form ng equation ay
#y = -25 (x-0.16) ^ 2-12.36 # Ans
