Mark the correct A. (1, 2)

B. (2, 3)

C. ((1, 3)

D. (2, 4)

Formula:- The necessary and sufficient condition for differentiable function defined on (a,b) to be strictly increasing on (a,b) is that f’(x)>0 for all x(a,b)

Given:-

f(x) = 2log(x – 2) – x² + 4x + 1

f^’(x)=

now for increasing

f^’(x)>0

3<0 and x-2>0

and x>2
