Understanding Function Rules and Order of Operations

The video tutorial explains how to write function rules using F of X by performing operations in different orders. It covers three parts: Part A involves multiplying by 3, adding 5, and dividing by 2; Part B involves adding 5, multiplying by 3, and dividing by 2; Part C involves dividing by 2, adding 5, and multiplying by 3. The tutorial emphasizes the importance of the order of operations in determining the function rule.

What is the first step in writing a function rule?

• Determine the output

• Select a function name

• Choose a variable

• Identify the operations involved

In Part A, what is the second operation performed on the input?

• Multiply by 3

• Add 5

• Divide by 2

• Subtract 5

How is the entire expression divided by 2 in Part A?

• Using a parenthesis

• Using a multiplication sign

• Using a fraction bar

• Using a subtraction sign

In Part B, what is the first operation performed on the input?

• Subtract 5

• Add 5

• Divide by 2

• Multiply by 3

What is the purpose of using parentheses in Part B?

• To make the expression longer

• To ensure correct order of operations

• To divide the expression

• To add clarity

In Part C, what is the first operation performed on the input?

• Subtract 5

• Add 5

• Multiply by 3

• Divide by 2

How is the multiplication by 3 ensured in Part C?

• By adding 3 to the expression

• By dividing by 3

• By placing 3 in front of the parentheses

• By using a fraction bar

What is the effect of changing the order of operations on a function rule?

• It simplifies the function rule

• It makes the function rule longer

• It changes the function rule

• It has no effect

Which part of the video discusses the impact of operation order on function rules?

• Conclusion

• Part A

• Part B

• Introduction

What is the main takeaway from the video regarding function rules?

• Function rules are not affected by input

• Function rules are always the same

• Order of operations is crucial

• Order of operations does not matter
