Question

if f(x) is a signum function then the value of f(-12)+f(24)+f(0) is
​

Answer 1

Answer:

$signum \: function \: f(x) = \frac{ |x| }{x} \\ so \: f( - 12) = \frac{ | - 12| }{ - 12} = \frac{12}{ - 12} = -1 \\ f(24) = \frac{ |24| }{24} = \frac{24}{24} = 1 \\ f(0) = \frac{ |0| }{0} = 0 \\ f( - 12) + f(24) + f(0) = - 1 + 1 + 0 = 0$
