What are the (x)-intercepts of the graph (y=|x^2-4|)?फलन (y=|x^2-4|) का (x)-अवरोध कौन-से हैं?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (x=-2) and (x=2)(x=-2) और (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.(x)-अवरोध के लिए (|x^2-4|=0), इसलिए (x^2-4=0)। मापांक शून्य तभी होता है जब अंदर का भाग शून्य हो।
