Question

The range of the function f(x)= sgn(x-[x])+1 is

Answer 1

Given:

f(x)= sgn(x-[x])+1

To find:

Range=?

Solution:

$sgn(x)= \left \{ {{x=-1} \atop {x=1}} \right.$

It implies that the given values is lie in between -1 to 1, that's why it's value are "-1,0, and 1".

The final answer is "-1, 0 , and 1".
