1.	If f(x) = x + 1, then write the value of
Answer» f(x) = x + 1 ⇒ (fof)(x) = f(x) + 1 = (x + 1) + 1 = x + 2 So, \(\frac{d}{d\text x}\)(fof)(x) = \(\frac{d}{d\text x}\)(x + 2) = 1

Answer»

f(x) = x + 1

⇒ (fof)(x) = f(x) + 1

= (x + 1) + 1

= x + 2

So, \(\frac{d}{d\text x}\)(fof)(x) = \(\frac{d}{d\text x}\)(x + 2)

= 1
