If f(x)= 1 x^ 1 / 4 (1+x^ 1 / 4 ) d x, f(0)=-6 , then f(1) is equal to :

Options

A4 ( _e 2-2 )
B2- _ e^2 2
C_ e 2+2
D4 ( _e 2+2 )

Correct answer

A. 4 ( _e 2-2 )

Step-by-step solution

aligned & Put x^ 1 / 4 =t d x=4 t^3 d t & 4 t^3 d t t(t+1) =4 ( t^2-1 t+1 + 1 t+1 ) d t & f(x)=4 [ x^ 1 / 2 2 -x^ 1 / 4 + |x^ 1 / 4 +1 | ]+C aligned aligned & f(0)=-6 & C=-6 & f(1)=4 ( _e 2-2 ) aligned
