यदि (p(x)=mx+n), (p(-1)=2) और (p(2)=11), तो (m) क्या है?
If (p(x)=mx+n), (p(-1)=2) and (p(2)=11), what is (m)?
Explanation opens after your attempt
B. (3)
Concept
Subtracting the two values gives (p(2)-p(-1)=3m=9). Therefore (m=3).
Why this answer is correct
The correct answer is B. (3). Subtracting the two values gives (p(2)-p(-1)=3m=9). Therefore (m=3).
Exam Tip
दोनों मान घटाने पर (p(2)-p(-1)=3m=9) मिलता है। इसलिए (m=3) है।
