1.Let lnx\ln xlnx denote natural log. Let S⊂RS\subset\mathbb RS⊂R be all points where ln(x2−1)\ln(x^2-1)ln(x2−1) is well-defined. Number of differentiable functions f:S→Rf:S\to\mathbb Rf:S→R with f′(x)=ln(x2−1)f'(x)=\ln(x^2-1)f′(x)=ln(x2−1) for x∈Sx\in Sx∈S and f(2)=0f(2)=0f(2)=0 isa.0b.1c.2d.infiniteLogin to continueOnly logged in users canattempt or see the solution.
