यदि (p(x)=mx+n), (p(1)=5) और (p(3)=13), तो (m) क्या है?
If (p(x)=mx+n), (p(1)=5) and (p(3)=13), what is (m)?
Explanation opens after your attempt
B. (4)
Concept
Subtracting the two values gives (p(3)-p(1)=2m=8). Therefore (m=4).
Why this answer is correct
The correct answer is B. (4). Subtracting the two values gives (p(3)-p(1)=2m=8). Therefore (m=4).
Exam Tip
दोनों मान घटाने पर (p(3)-p(1)=2m=8) मिलता है। इसलिए (m=4) है।
