For the signum function f(x) = sgn(x - 5), what is the graph value at x = 5?

Answer and explanation

Correct answer: 0

The governing concept is the piecewise definition of the signum function applied to a shifted input. For any real t, sgn(t) = -1 when t < 0, 0 when t = 0, and 1 when t > 0. At the specified point x = 5, the inner expression is x - 5 = 5 - 5 = 0. Therefore f(5) = sgn(0) = 0, making option B correct. The value -1 occurs on the branch x < 5, while 1 occurs on the branch x > 5; these describe the left and right horizontal portions of the graph, not the value at the jump point. The number 5 is the input coordinate, not the output. The graph includes the point (5, 0).
