Function Evaluation and Rules

The video tutorial explains how to fill in function tables using a two-step rule. The function rule given is y = 4 + 6x. The process involves substituting x values into the function to calculate corresponding y values. The tutorial demonstrates this with examples, using a calculator to find y values for different x inputs, and completes the table with these calculated values.

What is the function rule discussed in the video?

• y = 6 + 4x

• y = 6x + 4

• y = 4x + 6

• y = 4 + 6x

What is the first step in using the function rule to fill in the table?

• Multiply x by 6

• Subtract 4 from x

• Substitute x into the function

• Add 4 to x

What is the y value when x is 1?

• 12

• 4

• 6

• 10

What operation is performed after substituting x into the function?

• Division

• Subtraction

• Addition

• Multiplication

What is the result of 6 times 1 in the function?

What tool is suggested for calculating y when x is 3?

• A compass

• A calculator

• A protractor

• A ruler

What is the y value when x is 3?

• 20

• 18

• 22

• 24

What is the purpose of using a calculator in the video?

• To calculate y values

• To check the function rule
