यदि (f(x)=2x+3) और (\(f\circ f\)(x)=17), तो (x) का मान क्या है?

If (f(x)=2x+3) and (\(f\circ f\)(x)=17), what is the value of (x)?

Explanation opens after your attempt
Correct Answer

B. (2)

Step 1

Concept

(\(f\circ f\)(x)=f(2x+3)=2(2x+3)+3=4x+9).

Step 2

Why this answer is correct

(4x+9=17), so (4x=8).

Step 3

Exam Tip

Therefore, (x=2). चरण 1: (\(f\circ f\)(x)=f(2x+3)=2(2x+3)+3=4x+9)। चरण 2: (4x+9=17), इसलिए (4x=8)। चरण 3: अतः (x=2) है।
