Question

Which graph shows the axis of symmetry for the function f(x) = (x – 2)2 + 1?

On a coordinate plane, a vertical dashed line at (negative 2, 0) is parallel to the y-axis.
On a coordinate plane, a vertical dashed line at (2, 0) is parallel to the y-axis.
On a coordinate plane, a vertical dashed line at (negative 1, 0) is parallel to the y-axis.
On a coordinate plane, a vertical dashed line at (1, 0) is parallel to the y-axis.

Answer 1

The axis of symmetry is the vertical line x = 2 (passes through the vertex (2,1)). So choose: "On a coordinate plane, a vertical dashed line at (2, 0) is parallel to the y-axis."
