A curve `g(x)=intx^(27)(1+x+x^2)^6(6x^2+5x+4)dx` is passing through origin. Then (a)`g(1)=(3^7)/7` (b) `g(1)=(2^7)/7` (c)`g(-1)=1/7` (d)`g(-1)=(3^7)/(14)`

A

`g(1)=(3^(7))/(7)`

B

`g(1)=(2^(7))/(7)`

C

`g(-1)=(1)/(7)`

D

`g(-1)=(3^(7))/(14)`

Text Solution

Verified by Experts

The correct Answer is:
A, C

`g(x)=int x^(27)(1+x+x^(2))^(6)(6x^(2)+5x+4)dx`
`=int(x^(4)+x^(5)+x^(6))^(6)(6x^(5)+5x^(4)+4x^(3))dx `
`"Let " x^(6)+x^(5)+x^(4)=t " or "(6x^(5)+5x^(4)+4x^(3))dx=dt `
` :. g(x)=int t^(6)dt=(t^(7))/(7)+C=(1)/(7)(x^(4)+x^(5)+x^(6))^(7)+C `
`g(0)=0 impliesC=0 impliesg(1)=(3^(7))/(7) " and " g(-1)=(1)/(7)`
