Question 1/1 Easy Mathematics Relations and Functions Functions as a special kind of relation Class 11 Level 31

Explanation opens after your attempt
Correct Answer

A. 4

Explanation

Simple Explanation

दिए गए फलन में x=0 रखने पर (f(0)=4-0=4) प्राप्त होता है, इसलिए सही उत्तर 4 है। विकल्प B में फलन के मान के बजाय केवल x का मान लिया गया है। परीक्षा में (f(a)) निकालने के लिए फलन के सूत्र में x के स्थान पर a रखें। / Substituting x=0 into the function gives (f(0)=4-0=4), so the correct answer is 4. Option B is only the input value, not the function value. Exam tip: To find (f(a)), replace x by a in the given formula.
