यदि (f(x)=2x-1) और (g(x)=x-2) हों, तो ((f+g)(-2)) क्या होगा?
If (f(x)=2x-1) and (g(x)=x-2), what is ((f+g)(-2))?
Explanation opens after your attempt
A. (-1)
Concept
(f(-2)=-5) and (g(-2)=4), so the sum is (-1). The square of a negative number is positive.
Why this answer is correct
The correct answer is A. (-1). (f(-2)=-5) and (g(-2)=4), so the sum is (-1). The square of a negative number is positive.
Exam Tip
(f(-2)=-5) और (g(-2)=4), इसलिए योग (-1) है। ऋणात्मक संख्या का वर्ग धनात्मक होता है।
