यदि \(A={x\in R:2x-1\geq 5}\), तो (A) का अंतराल रूप क्या है?
If \(A={x\in R:2x-1\geq 5}\), what is the interval form of (A)?
Explanation opens after your attempt
B. \([3,\infty\))
Concept
Solve the inequality \(2x-1\geq 5\).
Why this answer is correct
\(2x\geq 6\), so \(x\geq 3\). Hence the interval is \([3,\infty\)).
Exam Tip
When \(\geq\) appears, include the starting endpoint. चरण 1: असमानता \(2x-1\geq 5\) को हल करें। चरण 2: \(2x\geq 6\), इसलिए \(x\geq 3\)। अतः अंतराल \([3,\infty\)) है। चरण 3: \(\geq\) होने पर आरंभिक छोर शामिल करें।
