રેખા \(y = 2x\) ને સમાંતર હોય અને વક્ર \(y = \mathop \smallint \limits_0^x \left| t \right|dt,x \in R\) ને સ્પર્શક હોય તેવી રેખાઓના \(x-\) અક્ષ પરનાં અંત:ખંડો મેળવો.

  1. A \( \pm 1\)
  2. B \( \pm 2\)
  3. C \( \pm 3\)
  4. D \(\; \pm 4\)
Verified Solution

Answer & Solution

Correct Answer

(A) \( \pm 1\)

Step-by-step Solution

Detailed explanation

\(\frac{{dy}}{{dx}} = \left| x \right| = 2\) \(x = \pm 2\) points \(y\int\limits_0^{ \pm 2} {\left| t \right|} dt = \pm 2\) \(\therefore \) equation of tangent is \(y-2=2(x-2)\) or \(y+2=2(x+2)\) \( \Rightarrow \) \(x\)- intercept \(\, = \pm 1\)
