Question

HElp Find the line of symmetry for the parabola whose equation is y = 2x∧2 - 4x + 1.

x = 2
x = -1
x = 1

Answer 1

x=1

Explanation:

because I said so

Answer 2

x = ---------- = 1

Explanation:

The formula for the axis of symmetry is x = -b/(2a). In this case b = -4 and a = 2, and so the axis of symmetry is

-(-4)

x = ---------- = 1
