Given : equation y = 4x^2 − 12x + 9

To Find  :

A) The axis of symmetry is x = 0 and the vertex is (0,9).

B)The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).

C)The axis of symmetry is x = 4 and the vertex is (4, -12).

D)The axis of symmetry is x = -1.5 and the vertex is (-1.5, 36).

Solution:

y =  4x² - 12x  + 9

=> y = (2x)² - 2(2x)3  + 3²

=> y = (2x - 3)²

=> y = 4(x - 3/2)²

=> y = 4(x - 1.5)²

Axis of symmetry is x= 1.5  

Vertex  = (1.5 , 0)

The axis of symmetry is x= 1.5 and the vertex is (1.5, 0).
