यदि (f(x)=4x-7) और (g(x)=x+2) हों, तो ((f-g)(x)) का मान क्या है?

If (f(x)=4x-7) and (g(x)=x+2), what is ((f-g)(x))?

Explanation opens after your attempt
Correct Answer

A. (3x-9)

Step 1

Concept

((f-g)(x)=f(x)-g(x)), so (4x-7-(x+2)=3x-9). Apply the minus sign to the whole (g(x)).

Step 2

Why this answer is correct

The correct answer is A. (3x-9). ((f-g)(x)=f(x)-g(x)), so (4x-7-(x+2)=3x-9). Apply the minus sign to the whole (g(x)).

Step 3

Exam Tip

((f-g)(x)=f(x)-g(x)), इसलिए (4x-7-(x+2)=3x-9)। ऋण चिह्न को पूरे (g(x)) पर लगाएं।
