1.Let x≠0x \ne 0x=0, ∣x∣<12|x| < \frac{1}{2}∣x∣<21 and f(x)=1+2x+4x2+8x3+…f(x) = 1 + 2x + 4x^2 + 8x^3 + \ldotsf(x)=1+2x+4x2+8x3+…. Then, f−1(x)=f^{-1}(x) =f−1(x)=a.x−12x\frac{x-1}{2x}2xx−1b.x−12\frac{x-1}{2}2x−1c.x−1x\frac{x-1}{x}xx−1d.1−2x1 - 2x1−2xLogin to continueOnly logged in users canattempt or see the solution.
