Question

Find the equation of the axis of symmetry for the parabola y=x^2-2x

Answer 1

x=1

Explanation:

Axis of symmetry is the straight line down the middle of the parabola. X-int. are at x=0 and x=2. 2-0/2=1.

Answer 2

Explanation:

y=x^2-2x

Find the vertex of the parabola (Using graphing form)

(x-1)^2-1

Vertex= (1,-1)

Line of symmetry: (-1,0)
