check attachment A

sir x axis pe intersect kiya woh kaise pata chala hoga woh bataein

f(0) = 0 hai so x - axis ko intersection karga

apne ko to only m ki values find karni hai iski jarurt hi nahi

solution kaise aaya woh me samaj gaya hu ache se pr f(0)=0 ye kaise aaya abhi bhi samaj nahi aaya mujhe

f(x) = sin³x-m sinx ,sin0 =0 therefore f(0)=0

understood now
