Question

Does anyone know how to explain this to me, please??

Answer 1

x = 1

Explanation:

The axis of symmetry is a vertical line passing through the vertex with equation

x = c ( c is the value of the x- coordinate of the vertex )

vertex = (1, - 1 ) with x- coordinate 1, then

x = 1 ← equation of axis of symmetry

Answer 2

Y=1 is the axis of symmetry
