The highlighted blue point is what you can use to identify the graph's

• axis of symmetry

• y-intercept

• vertex

• maximum

• minimum

Answer explanation

The point does not cross the y-axis so it is not a y-intercept. The point is also not a minimum because it's the highest point in the graph. This point can be used to find the axis of symmetry (x = x-coordinate of the vertex), the maximum (y-coordinate of the vertex), and the point, itself, IS the vertex.
