यदि किसी ग्राफ पर शून्यक (-2), (3), (7) हैं, तो (x)-अक्ष कटान बिंदुओं का सही समूह कौन सा है?
If a graph has zeroes (-2), (3), (7), which is the correct set of (x)-axis intersection points?
Explanation opens after your attempt
B. ((-2,0)), ((3,0)), ((7,0))
Concept
A zero (a) gives the intersection point ((a,0)). Tip: write the zero as the first coordinate.
Why this answer is correct
The correct answer is B. ((-2,0)), ((3,0)), ((7,0)). A zero (a) gives the intersection point ((a,0)). Tip: write the zero as the first coordinate.
Exam Tip
शून्यक (a) का कटान बिंदु ((a,0)) होता है। टिप: शून्यक को पहले निर्देशांक में लिखें।
