फलन (f(x)=x-3) और (g(x)=4x) के ग्राफों के प्रतिच्छेदों के (x)-मान कौन-से हैं?
What are the (x)-values of intersections of the graphs of (f(x)=x-3) and (g(x)=4x)?
Explanation opens after your attempt
A. (x=-2), (x=0), (x=2)
Concept
From \(x^3=4x\), we get (x\(x^2-4\)=0). In exams, equate the two functions for intersections.
Why this answer is correct
The correct answer is A. (x=-2), (x=0), (x=2). From \(x^3=4x\), we get (x\(x^2-4\)=0). In exams, equate the two functions for intersections.
Exam Tip
\(x^3=4x\) से (x\(x^2-4\)=0) मिलता है। परीक्षा में प्रतिच्छेद के लिए दोनों फलनों को बराबर करें।
