Answer 2

Explanation:

f(x) = 1 - x²

g(x) =
`√(11-4x)`

`((f)/(g))(x)=(f(x))/(g(x))`

`((f)/(g))(x)=(1-x^2)/(√(11-4x))`

`((f)/(g))(-1)=(1-(-1)^2)/(√(11-4(-1)))`

=
`(1-1)/(√(15))`

= 0

(g + f)(x) = g(x) + f(x)

=
`√(11-4x)+1-x^2`

(g + f)(2) =
`√(11-4(2))+1-(2)^2`

=
`√(3)-3`

(g - f)(x) = g(x) - f(x)

=
`√(11-4x)-(1-x^2)`

=
`√(11-4x)-1+x^2`

(g - f)(-1) =
`√(11-4(-1))-1+(-1)^2`

=
`√(15)`

(g . f)(x) = g(x) × f(x)

=
`(√(11-4x))(1-x^2)`

(g . f)(2) =
`(√(11-4(2)))(1-(2)^2)`

=
`√(3)(-3)`

= -3√3
