(a).Sketch a eraph of the function $f,$ (b). Determine an interval on which $f$ is one-to-one, (c).Find the inverse function of $f$ on the interval found in part (b), and (d) give the domain of the inverse function. (Note: There is more than one correct answer.)
$$f(x)=2 \sin x$$

Key Concepts

Domain and Range in the Context of Inverses

When a function is inverted, its original domain and range switch roles. Understanding how to determine these for both the original function and its inverse is crucial, as it ensures that the inverse function is correctly defined and that its domain accurately reflects the set of possible outputs from the original function.

Inverse Functions

The inverse function reverses the effect of the original function, mapping outputs back to their corresponding inputs. Finding an inverse function requires that the original function is one-to-one on the considered interval. The process typically involves solving for the input variable in terms of the output variable, essentially 'inverting' the function.

Graphing Trigonometric Functions

This concept involves understanding the behavior and characteristics of trigonometric functions, such as the sine function. It includes knowledge of amplitude, period, phase shift, and vertical translation, which are crucial for accurately sketching the graph of these functions.

One-to-One Functions and Domain Restriction

A function is one-to-one if every output is produced by a single input. Since trigonometric functions like sine are periodic and not one-to-one over their entire domain, it is necessary to restrict the domain to an interval where the function is monotonic (either strictly increasing or decreasing). This concept is essential for establishing the conditions under which a function can have an inverse.
