द्विघात बहुपद (p(x)=x-2+4) के ग्राफ के बारे में कौन सा कथन सही है?
Which statement is correct about the graph of the quadratic polynomial (p(x)=x-2+4)?
Explanation opens after your attempt
Correct Answer
A. यह (x)-अक्ष को नहीं काटताIt does not cut the (x)-axis
Concept
\(x^2+4\) is always positive so (y=0) never occurs. Count a zero only when the graph meets the axis.
Why this answer is correct
The correct answer is A. यह (x)-अक्ष को नहीं काटता / It does not cut the (x)-axis. \(x^2+4\) is always positive so (y=0) never occurs. Count a zero only when the graph meets the axis.
Exam Tip
\(x^2+4\) हमेशा धनात्मक है इसलिए (y=0) नहीं होता। ग्राफ से शून्यक तभी मानें जब अक्ष से मिलन हो।
