Find the axis of symmetry and the vertex of the graph of f (0) = 4x^2 - 8x + 3. i need the axis of symmetry, and the vertex

Vertex: (1,-1)

Symmetry: x = 1

Step-by-step explanation:

y = 4x² - 8x + 3

y = 4 (x² - 2x) + 3

y = 4[x² - 2 (x) (1) + 1² - 1²] + 3

y = 4 (x - 1) ² - 1

In y = a (x - h) ² + k,

(h, k) is the vertex

And a vertical line passing through the vertex is the line of symmetry, i. e x = h.

Vertex: (1,-1)

Symmetry: x = 1
