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
Correct Answer

A. (18)

Step 1

Concept

((f+g)(x)=4x-2+2), so ((f+g)(-2)=4\cdot4+2=18). Adding functions first makes calculation easier.

Step 2

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.

Step 3

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।
