Composite functions

The video tutorial introduces composite functions, explaining their real-world applications and the importance of order in solving them. It provides examples and exercises to illustrate how to solve composite function problems, including algebraic substitution. The tutorial concludes with a brief mention of inverse functions and encourages viewers to engage with further content.

What is a composite function?

• A function that only uses addition and subtraction.

• A function that does not depend on the order of operations.

• A function that combines multiple functions in a specific order.

• A function that is made up of a single operation.

Why is the order important in composite functions?

• Because it changes the type of function used.

• Because it affects the speed of calculation.

• Because it simplifies the function.

• Because it determines the final result of the function.

How do you read composite functions?

• From bottom to top.

• From right to left.

• From top to bottom.

• From left to right.

What is the result of substituting 2x - 3 into F(x)?

• x + 3

• 2x - 3

• x - 3

• 2x + 3

What should you remember when combining multiple functions?

• To read from left to right.

• To use only two functions.

• To read from right to left.

• To use only addition.
