Question
I need help solving these two problems
![### Identifying and Graphing Quadric Surfaces
#### Problem:
Identify the following quadric surfaces, and sketch a graph using at least three traces for each surface. **Do not** use technology to graph these.
#### Exercises:
**(a)**
\[ z = 4 - x^2 - y^2 \]
- **Surface:**
- **Graph:**
**(b)**
\[ x^2 + y^2 - z^2 = -3 \]
- **Surface:**
- **Graph:**
For each problem, identify the type of quadric surface and then create a graph using at least three traces to represent the surface.
In the context of the exercise:
- **Surface:** Provide the name/type of the quadric surface (e.g., ellipsoid, hyperboloid, etc.)
- **Graph:** Include sketches of the surface based on the provided equation, using at least three specific traces (i.e., cross-sections) to display the shape of the surface effectively.
This exercise encourages understanding of three-dimensional surfaces without relying on graphing calculators or software. Make sure to interpret each equation to its canonical form, if necessary, and then proceed to sketch the traces that help identify the surface.](https://content.bartleby.com/qna-images/question/34cf04e3-0e6a-47ff-a4e0-f99b5389fcbb/295bb6f0-3d6b-4794-8b2e-2654e0235424/cnz5w5s_processed.png)
