यदि (f(x)=3x-2-2) और (g(x)=x-2+4) हैं, तो ((f+g)(-2)) का मान क्या होगा?
If (f(x)=3x-2-2) and (g(x)=x-2+4), what is the value of ((f+g)(-2))?
Explanation opens after your attempt
A. (18)
Concept
((f+g)(x)=4x-2+2), so ((f+g)(-2)=4\cdot4+2=18). Adding functions first makes calculation easier.
Why this answer is correct
The correct answer is A. (18). ((f+g)(x)=4x-2+2), so ((f+g)(-2)=4\cdot4+2=18). Adding functions first makes calculation easier.
Exam Tip
((f+g)(x)=4x-2+2), अतः ((f+g)(-2)=4\cdot4+2=18)। पहले फलनों को जोड़ना गणना को आसान बनाता है।
