एक ग्राफ (x)-अक्ष के ऊपर ही रहता है और उसे कहीं नहीं काटता। उस बहुपद के वास्तविक शून्यक कितने हैं?
A graph stays entirely above the (x)-axis and never cuts it. How many real zeroes does that polynomial have?
Explanation opens after your attempt
Correct Answer
A. शून्यZero
Concept
When the graph does not meet the (x)-axis, (p(x)=0) never occurs. Tip: a real zero is seen on the (x)-axis.
Why this answer is correct
The correct answer is A. शून्य / Zero. When the graph does not meet the (x)-axis, (p(x)=0) never occurs. Tip: a real zero is seen on the (x)-axis.
Exam Tip
जब आलेख (x)-अक्ष से नहीं मिलता तो (p(x)=0) नहीं होता। टिप: वास्तविक शून्यक हमेशा (x)-अक्ष पर दिखता है।
