In Algebra 1a, Unit 4: Functions, Lesson 25, you will likely cover various topics related to functions. However, without specific information about the curriculum or textbook you are using, I can provide a general overview of what you might expect to learn in this lesson.

1. Introduction to Composite Functions: You may learn how to combine two or more functions to form a new function called a composite function. This involves substituting one function into another and understanding how the composition affects the input and output values.

2. Composite Function Notation: In this lesson, you might learn about the notation used to represent composite functions. It typically involves representing the composition of two functions f and g as (f ∘ g)(x).

3. Evaluating Composite Functions: You will likely practice evaluating composite functions for specific input values. This involves substituting the given value into the innermost function and then applying the outer function.

4. Finding the Domain and Range of Composite Functions: You may learn how to determine the domain and range of a composite function based on the domains and ranges of the individual functions involved.

5. Applications of Composite Functions: This lesson might also include real-life applications of composite functions. For example, you might see how composite functions can be used to model scenarios involving time, distance, velocity, or other variables.
