यदि \(f:\mathbb{R}\to\mathbb{R}\) को (f(x)=\begin{cases}3x-2,&x<4\x-2-10,&x\ge4\end{cases}) से दिया गया है, तो (f(4)) क्या है?
If \(f:\mathbb{R}\to\mathbb{R}\) is given by (f(x)=\begin{cases}3x-2,&x<4\x-2-10,&x\ge4\end{cases}), what is (f(4))?
Explanation opens after your attempt
A. (6)
Concept
The input (x=4) belongs to the second part, so (f(4)=42-10=6). Choose the correct rule by reading the boundary sign.
Why this answer is correct
The correct answer is A. (6). The input (x=4) belongs to the second part, so (f(4)=42-10=6). Choose the correct rule by reading the boundary sign.
Exam Tip
(x=4) दूसरे भाग में आता है, इसलिए (f(4)=42-10=6) है। सीमा चिह्न देखकर सही नियम चुनें।
