 As we have learned

Properties of differentiable functions -

The sum, difference, product and quotient of two differentiable functions is differentiable.

-

 

\because   f(x) is product of various diffrentiable functions so , it will be also diffrentiable at all x\epsilon R

\therefore no. of required points = zero
