Step-by-step explanation:
The triangle shown in the image attached is a right triangle.
Therefore, you can calculate the value of <em>x</em> as you can see below:

In this case, you have that:
<em> adjacent=x</em>
<em> hypotenuse=11</em>

Therefore, when you substitute values and solve for <em>x</em>, you obtain the following result:

Step-by-step explanation:
1. The domain D and range R of the given function are given by: D: (- ∞ , + ∞) and R: (- ∞ , + ∞)
2. In order to find the inverse, we first write the function as an equation as follows. ...
3. Then solve it starting by cubing both sides. ...
4. Simplify and solve for x. ...
5. Change x into y and y into x to obtain the inverse function.
Answer:
