How is domain of the function f(x)=cosx restricted so that its inverse function exists? Drag a value or interval into each box to correctly complete the statements.
The domain of f(x)=cosx is restricted to _____so that the inverse of the function exists. This means that all functional values of f(x)=cos^(−1)x are on the interval _____ .
(-π/2,π/2) [-π/2,π/2] (0,π) [0,π] (0,2π) [0,2π]
+36916 (-π/2,π/2) [-π/2,π/2] (0,π) [0,π] (0,2π) [0,2π]
[1, +inf) I think.....all of the other intervals listed would have a cos x value of zero included which would result in a zero denominator.
