यदि (p(x)=(x-2)2(x+5)2) है, तो ग्राफ (x)-अक्ष के साथ कैसा व्यवहार करेगा?
If (p(x)=(x-2)2(x+5)2), how will the graph behave with the (x)-axis?

Correct Answer
B. दोनों शून्यकों पर स्पर्श करेगाIt will touch at both zeroes
Concept
Both factors have even powers, so the graph touches at both points. Tip: at an even power the graph usually turns back.
Why this answer is correct
The correct answer is B. दोनों शून्यकों पर स्पर्श करेगा / It will touch at both zeroes. Both factors have even powers, so the graph touches at both points. Tip: at an even power the graph usually turns back.
Exam Tip
दोनों कारक सम घात में हैं, इसलिए दोनों बिंदुओं पर स्पर्श होगा। टिप: सम घात पर ग्राफ सामान्यतः दिशा बदलता है।
