फलन (f(x)=|x+4|-2) के ग्राफ का शीर्ष बिंदु कौन सा है?
Which point is the vertex of the graph of (f(x)=|x+4|-2)?
Explanation opens after your attempt
A. ((-4,-2))
Concept
Set the inside of the modulus (x+4=0), so (x=-4). Then (y=-2), so the vertex is ((-4,-2)).
Why this answer is correct
The correct answer is A. ((-4,-2)). Set the inside of the modulus (x+4=0), so (x=-4). Then (y=-2), so the vertex is ((-4,-2)).
Exam Tip
मापांक के अंदर (x+4=0) करने पर (x=-4) मिलता है। तब (y=-2) है इसलिए शीर्ष ((-4,-2)) है।
