Let's address the questions one by one from the image you provided:

**(b) What is a relation? What is a function? Given that \( g(m) = 32m^2d + 16\sqrt{m} \), which symbol represents the independent variable? Dependent variable? Parameter?**

- A **relation** is a set of ordered pairs, where each element from one set is related to an element from another set. For example, in a relation \( R \), if \( (x, y) \in R \), it means that \( x \) is related to \( y \).
  
- A **function** is a special type of relation where each input (independent variable) is associated with exactly one output (dependent variable). In other words, for every value of \( x \), there is exactly one value of \( f(x) \).
  
- In the given function \( g(m) = 32m^2d + 16\sqrt{m} \):
  - The **independent variable** is \( m \) since \( g(m) \) is written in terms of \( m \) (the input).
  - The **dependent variable** is \( g(m) \) (the output depends on \( m \)).
  - The **parameter** could be \( d \), since it's a constant that might be assigned a value independently of \( m \).

**(c) What is the purpose of the vertical line test?**

The **vertical line test** is used to determine if a graph represents a function. If a vertical line intersects the graph at more than one point, the relation is not a function, because a single input (x-value) is associated with multiple outputs (y-values), which violates the definition of a function.

---

**(d) What is the natural domain of a function? What is the given domain of a function?**

- The **natural domain** of a function is the set of all possible input values (x-values) for which the function is defined. For example, for \( f(x) = \sqrt{x} \), the natural domain is \( x \geq 0 \) because the square root is undefined for negative values.
  
- The **given domain** of a function is a specific subset of the natural domain that is imposed or restricted. For instance, the function might be defined as \( f(x) = \sqrt{x} \) only for \( x \in [1, 10] \), even though its natural domain is \( x \geq 0 \).

---

**(e) What is the graph of a function?**

The **graph of a function** is the visual representation of all the ordered pairs \( (x, f(x)) \) on a coordinate plane. Each point on the graph corresponds to an input \( x \) and its corresponding output \( f(x) \), showing how the function behaves.

Let me know if you would like more details on any of these concepts. Here are some follow-up questions:

1. Can you give an example of a relation that is not a function?
2. How can you tell if an equation represents a function without graphing it?
3. How does the vertical line test relate to the definition of a function?
4. Can the natural domain of a function ever be larger than the given domain?
5. How do you graph a function like \( g(m) = 32m^2d + 16\sqrt{m} \)?

**Tip**: When dealing with functions, always check if the function is defined for all inputs in the domain to avoid errors in calculation.

What is a relation? What is a function? Given that g(m) = 32m^2d + 16√m, which symbol represents the independent variable? Dependent variable? Parameter?

This page covers relations, functions, and the identification of independent and dependent variables using the function g(m) = 32m^2d + 16√m. Suitable for high school students (Grades 9-12). It also explains the vertical line test and the concept of the natural domain.
