JEE Mains · Maths · STD 12 - 7.2 definite integral

જો \(f : R \to R\) એ વિધેય આપેલ છે કે જેથી  દરેક  \(x \in  R\) માટે \(f(2 - x)\, = f(2 + x)\) અને \(f(4 -x)\, = f(4 + x)\) અને \(\int\limits_0^2 {f\left( x \right)\,dx = 5} \) તો \(\int\limits_{10}^{50} {f\left( x \right)\,\,dx} \) મેળવો.

  1. A \(125\)
  2. B \(80\)
  3. C \(100\)
  4. D \(200\)

Answer & Solution

Correct Answer

(C) \(100\)

Step-by-step Solution

Detailed explanation

Let \(f: R \rightarrow R\) be a function such that \(f(2-x)\) \(=f(e+x)\) Put \(x=2+x\) we get \(f(-x)=f(4+x)=f(4-x)\) \(\Rightarrow f(x)=f(x+4)\) Hence period is 4 Consider \( = \int\limits_{10}^{50} {f\left( x \right)dx} \)…
