यदि किसी परवलय का शीर्ष ((-5,0)) है तो वास्तविक शून्यकों की अलग संख्या क्या होगी?
If the vertex of a parabola is ((-5,0)), what will be the distinct number of real zeroes?
Explanation opens after your attempt
Correct Answer
B. एकOne
Concept
The vertex lies on the (x)-axis, so the parabola touches at ((-5,0)). Tip: if the vertex has (y=0), there is one distinct zero.
Why this answer is correct
The correct answer is B. एक / One. The vertex lies on the (x)-axis, so the parabola touches at ((-5,0)). Tip: if the vertex has (y=0), there is one distinct zero.
Exam Tip
शीर्ष (x)-अक्ष पर है इसलिए परवलय ((-5,0)) पर स्पर्श करेगा। टिप: शीर्ष का (y)-मान (0) हो तो एक अलग शून्यक होता है।
