Match List-I with List-II. Here [x] denotes the greatest integer function
Choose the correct answer from the options given below: |
(A)-(I), (B)-(II), (C)-(III), (D)-(IV) (A)-(II), (B)-(III), (C)-(IV), (D)-(I) (A)-(III), (B)-(IV), (C)-(I), (D)-(II) (A)-(IV), (B)-(I), (C)-(II), (D)-(III) |
(A)-(II), (B)-(III), (C)-(IV), (D)-(I) |
The correct answer is Option (2) → (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
$\textbf{(A)}\; f(x)=\lfloor x \rfloor$ The greatest–integer function has jump discontinuities at every integer. So it matches: “continuous everywhere except at all integral values.” $A \to (II)$ $\textbf{(B)}\; f(x)=|x-1|$ Absolute value functions are continuous everywhere but not differentiable where the inside becomes zero → at $x=1$. So it matches: “continuous everywhere but not differentiable at $x=1$.” $B \to (III)$ $\textbf{(C)}\; f(x)=e^{|x|}$ Continuous everywhere, but $|x|$ is not differentiable at $x=0$, so $e^{|x|}$ is also not differentiable at $x=0$. So it matches: “continuous everywhere but not differentiable at $x=0$.” $C \to (IV)$ $\textbf{(D)}\; f(x)=|x+1|$ Non-differentiable where $x+1=0$ → at $x=-1$. So it matches: “continuous everywhere but not differentiable at $x=-1$.” $D \to (I)$ $\textbf{Final Answer: } A\to II,\; B\to III,\; C\to IV,\; D\to I$ |
