Answer:

The statement is false as it depends on the domain

Step-by-step explanation:

We are given the statement,

For a trigonometric function y=f(x) implies x=f^{-1}(y).

<em>This statement is not always true.</em>

For example,

The function y=\sin x is one-one and onto in the domain [-\frac{\pi}{2},\frac{\pi}{2}].

Thus, its inverse exists in [-\frac{\pi}{2},\frac{\pi}{2}].

That is, in [-\frac{\pi}{2},\frac{\pi}{2}], y=\sin x implies x=\sin^{-1}(y).

Hence, we see that,

<em>It depends on the domain for the given statement to be true.</em>

Thus, the statement is false.
