Question

What is the range of a signum function?​

Answer 1

Answer: This may help you

Step-by-step explanation:

Range of signum function is { -1, 0, 1 } since it only takes these three values. From the graph, we can infer that, Signum function is continuous everywhere except at x = 0. Signum function is not differentiable at x = 0.

Answer 2

Answer:

Signum function is defined from real numbers to real numbers. The domain of the signum function is mathematics is complete real numbers but range of the function restricts only in 3 results : (-1,0,1). And there are condition when the range is -1, when 0 or when 1
