यदि (f(x)=2x+3) और (g(x)=\frac{x-3}{2}) हैं तो (\(f\circ g\)(x)) क्या है?
If (f(x)=2x+3) and (g(x)=\frac{x-3}{2}) then what is (\(f\circ g\)(x))?
Explanation opens after your attempt
Correct Answer
A. (x)
Concept
(\(f\circ g\)(x)=2\left\(\frac{x-3}{2}\right\)+3=x). This shows the two functions behave like inverses of each other.
Why this answer is correct
The correct answer is A. (x). (\(f\circ g\)(x)=2\left\(\frac{x-3}{2}\right\)+3=x). This shows the two functions behave like inverses of each other.
Exam Tip
(\(f\circ g\)(x)=2\left\(\frac{x-3}{2}\right\)+3=x)। यह दिखाता है कि दोनों फलन परस्पर प्रतिलोम जैसे काम कर रहे हैं।
