If (f:\mathbb{R}\to\mathbb{R}) is given by (f(x)=\begin{cases}x^2,&x<1\2x-1,&x\ge1\end{cases}), which statement is correct?यदि (f:\mathbb{R}\to\mathbb{R}) को (f(x)=\begin{cases}x^2,&x<1\2x-1,&x\ge1\end{cases}) से दिया गया है तो कौन सा कथन सही है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: It is a function and (f(1)=1)यह फलन है और (f(1)=1)
The point (x=1) belongs only to the second part, and (f(1)=2\cdot1-1=1). Read boundary symbols carefully in piecewise functions.(x=1) केवल दूसरे भाग में आता है और (f(1)=2\cdot1-1=1) है। खंडित फलन में सीमा चिह्न सावधानी से पढ़ें।
