What is the local maximum value of f(x)=x^3-3144x?
f(x)=x^3-3144x का local maximum value क्या है?
Show answer and explanation
Correct Answer
B. 3456
ExplanationStep 1: the critical point for maximum is x=-12. Step 2: f(-12)=(-12)^3-3144(-12)=3456. Step 3: tip: for x^3-3a^2x, maximum value is 2a^3.
Step 1: critical point for maximum x=-12 है। Step 2: f(-12)=(-12)^3-3144(-12)=3456। Step 3: tip: x^3-3a^2x में maximum value 2a^3 होती है।
