1.Let f:R→Rf:\mathbb{R}\to\mathbb{R}f:R→R be f(x)=sin(∣x∣)f(x)=\sin(|x|)f(x)=sin(∣x∣). Which is correct?a.fff is not differentiable only at 0b.fff is differentiable at 0 onlyc.fff is differentiable everywhered.fff is non-differentiable at many pointsLogin to continueOnly logged in users canattempt or see the solution.
