WebCorrect option is C) We know that if f(x)>0 then f is increasing on that interval and if f(x)<0 then f is decreasing on the interval. Given f(x)= sinxx. f(x)= sin 2xsinx−xcosx=0. sinx−xcosx=0. x= cosxsinx=tanx. In the interval (0,1) there is no solution for x=tanx. Therefore, f(x)>0. Webf (x) = ex ⋅ sin(x) f ( x) = e x ⋅ sin ( x) Find the first derivative. Tap for more steps... f '(x) = excos(x)+ exsin(x) f ′ ( x) = e x cos ( x) + e x sin ( x) Find the second derivative. Tap for more steps... f ''(x) = 2excos(x) f ′′ ( x) = 2 e x cos ( x) The second derivative of f (x) f ( x) with respect to x x is 2excos(x) 2 e x cos ( x).
