फलन \(y=|x^2-4|\) का (x)-अवरोध कौन-से हैं?
What are the (x)-intercepts of the graph \(y=|x^2-4|\)?
Explanation opens after your attempt
A. (x=-2) और (x=2)(x=-2) and (x=2)
Concept
For (x)-intercepts, \(|x^2-4|=0\), so \(x^2-4=0\). An absolute value is zero only when its inside is zero.
Why this answer is correct
The correct answer is A. (x=-2) और (x=2) / (x=-2) and (x=2). For (x)-intercepts, \(|x^2-4|=0\), so \(x^2-4=0\). An absolute value is zero only when its inside is zero.
Exam Tip
(x)-अवरोध के लिए \(|x^2-4|=0\), इसलिए \(x^2-4=0\)। मापांक शून्य तभी होता है जब अंदर का भाग शून्य हो।
