Question

If f(x) be a signum function, then find the value of f(x) at x = 5.​

Answer 1

Answer:

The value of f(x) at x=5 is 1

Step-by-step explanation:

Conept used:

Signum function:

$f(x)=\frac{x}{|x|}\:if\:x\neq0$

$\:\:\:\:=0\:\:\:if\:x=0$

clearly,

Range of f is { -1, 0, 1}

At x=5,

$f(x)=\frac{5}{|5|}$

$f(x)=\frac{5}{5}$

$f(x)=1$
