Ano ang axis ng simetrya at vertex para sa graph y = x ^ 2 - 4x + 2?

Sagot:

Vertex #(2,-2)#

axis of symmetry # x = 2 #

Paliwanag:

Given -

# y = x ^ 2-4x + 2 #

Vertex

#x = (- b) / (2a) = (- (- 4)) / (2xx1) = 4/2 = 2 #

Sa # x = 2; y = 2 ^ 2-4 (2) + 2 #

# y = 4-8 + 2 = -2 #

Vertex #(2,-2)#

axis of symmetry # x = 2 #
