what is real valued function? plzz..xplain with a simple example...!!

Hi Ranjita,

Real Valued functions are those functions that have real arguments (domain) and return a real value upon evaluation (range).

y = f(x).

x is real and y is real.

There could be numerous examples.

y=x^2, y=sinx.... etc.
