Find the vertex point,domain and range please and thank you

Question

Identify the vertex point and the domain and range for the equation

y=4x*2-8x+9

Answer 1

4x² - 8x + 9

This a parabola that opens upwards and crosses the y-axis at (0,9)

In the form of y = ax² + bx + c, the Axis of Symmetry is given by x = -b/2a, which is x = 8/8 = 1

Then this is vertex point of (1, 5).

The Domain is all real numbers, the Range is ≥ 5
