    @chinkuchawdhary8017 Před 5 lety +11

    Isn't there an error in the last question , the interval of x is given to be -1/2 to 1/2 , so the value of the function will always remain positive , so it must be one one

    In the third case 2x-1 is +ve for x belongs to (1/2-infinity) but also the domain of the function is the subset of this interval.So 2x-1 is always +ve in the given function right??
