Answer:

Step-by-step explanation:
The Cylindrical coordinates are:
x = rcosθ, y = rsinθ and z = z
From the question, on the xy-plane;


where:
0 ≤ r ≤
and 0 ≤ θ ≤ 2π
∴












The y-intercept of the function is at y = -3 so the options that don’t include it are off the table. The only possible answer is option C. Option A doesn’t work because plugging in positive values would give negative numbers within the square root which isn’t defined in the real numbers.

Answer: OPTION C.
Step-by-step explanation:
In order to solve the given exercise, you can follow these steps:
1. Given the following function f(x):

You must substitute
into the function f(x). Then:

2. Evaluating, you get:

3. Now, the next step is to substitute
into the function g(x):

4. Finally, evaluating, you get the following result:

You can identify that it matches with the Option C.
