If (f(x)=\frac{x^2-4}{x+2}) and (g(x)=x-2), which statement about ((f-g)(-2)) is correct?यदि (f(x)=\frac{x^2-4}{x+2}) और (g(x)=x-2) हैं, तो ((f-g)(-2)) के बारे में सही कथन क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Undefinedअपरिभाषित
In (f), the denominator is zero at (x=-2), so (f) and (f-g) are undefined. Check the original domain before simplification.(f) में (x=-2) पर हर शून्य है, इसलिए (f) और (f-g) अपरिभाषित हैं। सरलीकरण से पहले मूल प्रांत देखें।
