The graph of a quadratic function is given below. What is equation of the line that represents the
axis of symmetry?
f(x)

x = - 1

Step-by-step explanation:

Because this a vertically opening parabola, then the axis of symmetry is a vertical line with equation

x = c

where c is the value of the x- coordinates the line passes through.

The axis of symmetry passes through the vertex (- 1, 16) with x- coordinate - 1

Thus the equation of the axis of symmetry is x = - 1
