Question

hlo guys..... explain Signum function with graph.... ❤​

Answer 1

it works dude

thank all my answers dear

Answer 2

Signum function:-

This function says that for all x > 0, y = 1 and for all x < 0, y= -1. The function is written is f(x) = |x|/x , where x is not equal to 0.

Let us check value of f(x)

for different values

For x = -1

x is smaller than 0

so, f(x) = -1

For x = -2

x is smaller than 0

so, f(x) = -1

For x = 1

x is greater than 0

so, f(x) = 1

For x = 2

x is greater than 0

so, f(x) = 1

For x = 0

x is equal to 0

so, f(x) = 0
