In a graph, the basic absolute value function has the following characteristics.

  • The graph of an absolute value function is symmetrical.

  • For the basic absolute value function, the axis of symmetry is the line of equation |x = 0.|

  • The vertex of the graph of the basic absolute value function is the point |(0, 0).|

  • The left branch has the equation |y=-x| and the right branch has the equation |y=x.|
