Ano ang vertex form ng y = x ^ 2 - 5x + 4?

Sagot:

Form ng Vertex # (x-5/2) ^ 2 = y - 9/4 #

Paliwanag:

mula sa ibinigay # y = x ^ 2-5x + 4 #

kumpletuhin natin ang parisukat

# y = x ^ 2-5x + 25 / 4-25 / 4 + 4 #

# y = (x ^ 2-5x + 25/4) -25 / 4 + 16/4 #

# y = (x-5/2) ^ 2-9 / 4 #

# y + 9/4 = (x-5/2) ^ 2 #

din

# (x-5/2) ^ 2 = y - 9/4 #

graph {y = x ^ 2-5x + 4 -20,20, -10,10}

magandang araw!
