Question

What is the axis of symmetry for the function shown in the graph?

(*1,4)

(1,-4)

(1,4)

(-1,3)

​

Answer 1

x = 1

Explanation:

The axis of symmetry for a vertically opening parabola is a vertical line with equation

x = h

where h is the value of the x- coordinate the line passes through.

The axis of symmetry passes through the vertex 1, 4 ) with x- coordinate 1

Hence equation of axis of symmetry is x = 1
