A linear function, which is minimized or maximized is called an optimal point.

Answer

To determine whether the statement "A linear function, which is minimized or maximized is called an optimal point" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Terms**:
- A **linear function** is a function of the form \( z = ax + by + c \), where \( a \), \( b \), and \( c \) are constants.
- An **objective function** is the function that we aim to maximize or minimize in a linear programming problem.

2. **Identifying the Statement**:
- The statement claims that a linear function that is minimized or maximized is called an "optimal point."

3. **Clarifying the Concept of Optimal Point**:
- An **optimal point** refers to the specific values of the variables (such as \( x \) and \( y \)) that yield the maximum or minimum value of the objective function.
- It is not the function itself that is called the optimal point, but rather the point (or points) at which the maximum or minimum occurs.

4. **Conclusion**:
- Since the statement incorrectly identifies a linear function as an optimal point, the statement is **false**. The correct terminology is that the maximum or minimum value of the objective function occurs at the optimal point, not that the function itself is called an optimal point.

### Final Answer:
The statement is **false**.
