The domain of definition of f(X) = `sin^(-1)(-x^(2))` isA. `[-1,1]`B. `[0,1]`C. `[-1,0]`D. `[-2,23]`

Answer» The domain of `sin^(-1)x is [-1,1]` Therefore f(x)=`sin^(-1)(-x^(2))` is defined for all x satisfying
`-1le-x^(2)le1`
`rarr 1gex^(2)-1rarr 0lex^(2)le1rarrx^(2)le1rarr x^(2)-1le0`
`rarr (x-1)(x+1)le0rarr-1lexle1`
Hence the domain of f(X)=`sin^(-1)(-x^(2))` is [-1,1]
