How is the domain of a trigonometric function restricted so that its inverse function is defined?

 

The graph of f(x)=tanx _____. Therefore, a domain restriction must be placed on the function of the inverse function to be defined. The domain restriction placed on f(x)=tanx is ________ so that its inverse function is defined.

 

passes the vertical line test

passes the horizontal line test

is not one-to-one

 

(-π/2, π/2)

(0,π/2)

(0,π)

[-π/2,π/2]

[0,π/2]
