Question
Suppose f(x) is differentiable x = 1 and 
f(1 + h) = 5, then f′(1) equals

f(1 + h) = 5, then f′(1) equalsOptions
A.3
B.4
C.5
D.6
Solution
f′(x) =
; As function is differentiable so it is continuous as it is given
that
= 5 and hence f(1) = 0
Hence f′(1) =
= 5
Hence (3) is the correct answer.
