Answer 2

Answer:

[0,1]

Step-by-step explanation:

We have to calculate the domain of definition of the function f(x) = Cos⁻¹x.

We have to get all the values of x for which the function f(x) is defined.

Let us rearrange the equation as Cos f(x) =x.

Now, we all know that for any value of f(x), Cos f(x) i.e. x value ranges between -1 to 1.

Here, x is positive, therefore, the required domain is [0,1]. (Answer)
