यदि परवलय (x)-अक्ष को दो बिंदुओं पर काटता है और (y)-अक्ष को ((0,-15)) पर काटता है, तो वास्तविक शून्यकों की संख्या क्या है?
If a parabola cuts the (x)-axis at two points and cuts the (y)-axis at ((0,-15)), what is the number of real zeroes?
Explanation opens after your attempt
Correct Answer
B. दोTwo
Concept
Real zeroes are counted from (x)-axis intersections, not from the (y)-axis intercept. Tip: ((0,-15)) does not show a zero.
Why this answer is correct
The correct answer is B. दो / Two. Real zeroes are counted from (x)-axis intersections, not from the (y)-axis intercept. Tip: ((0,-15)) does not show a zero.
Exam Tip
वास्तविक शून्यक (x)-अक्ष कटानों से गिने जाते हैं, (y)-अक्ष कटान से नहीं। टिप: ((0,-15)) शून्यक नहीं बताता।
