Let f(x) be a real valued function such that the area of an equilateral triangle with two of its vertices at (0, 0) and (x, f(x)) is (sqrt(3))/(4) square units. Then f(x) is given by

`sqrt(2-x^(2))`

`sqrt(1+x^(2))`

`sqrt(1-x^(2))`

`+- sqrt(2- x^(2))`

`[1, oo)`

`[-oo, 1)`

`(-1, 1)`

`[-1, 1]`

`pm sqrt(1-x^(2))`

`-sqrt(1-x^(2)) or sqrt(1-x^(2))`

`sqrt(1-x^(2))` only

`sqrt(1+x^(2))`
