I select students at random from name sticks to help me fill in the data table for this function.

Is there an easier way to find the y-intercept if the student calculates the y-intercept? I use this strategy to give appropriate support to my struggling students without letting them off the hook for the learning.

Got It The student provides complete and correct responses to all components of the task. Questions Eliciting Thinking Can you check your slope calculation again?

There were three students who finished very quickly, so I assigned them IXL math online another assignment of function tables to solve to keep them challenged. Neglects to use function notation or uses it incorrectly.

The student does not understand the basic form of a linear function. Almost There The student makes a calculation or other minor error. I remind students that we have actually been writing function rules the past few days with Turtle and Snail. When the time sounds, I ask for a volunteer to share.

Instructional Implications Be sure the student understands the role of the slope and y-intercept in writing the equation of a line in slope-intercept form.

How can you use the slope and y-intercept to write the equation? Did you check if the ordered pairs in the table satisfy your equation? If needed, review function notation and guide the student to use function notation when writing equations of lines. The friend must conduct a "whisper conference" where they have been trained to give tips instead of just telling the answer.

If needed, review how to calculate the slope of a line given two points on a line. Explain that function rules for arithmetic sequences are linear functions. Solution We can notice that the letters provided as output are the last letters in the words provided as input, so one possible rule is "take the last letter" of the input.

Remind the student of the terminology used in the context of sequences e. What is function notation? Once the problem is finished, the paper passes to the other partner who then coaches. Questions Eliciting Thinking I see that you found a common difference of four for the first sequence.

The act of guessing what someone is thinking is not really mathematics, but mirrors the process one often goes through when modeling with mathematics. Students need to learn that there are patterns to the rule related to patterns of the output.

Questions Eliciting Thinking How did you know that 0, 2 was the y-intercept if the student identifies the y-intercept in the table?

Okaloosa Is this Resource freely Available? Provide additional examples of arithmetic and geometric sequences and ask the student to write function rules.

Makes a calculation error when calculating the slope. Questions Eliciting Thinking Is the notation you used consistent with the notation given in the problem? I then explained that during the next lesson, we will continue to write functions, but that we will be using them to make decisions about how to spend money.

Questions Eliciting Thinking Is the second sequence arithmetic? For example, in Scrabble every word has at least two letters, so a second-letter function would be well-defined there. SB file This lesson works at satisfying the standard 4. What is always true of the y-intercept?

What kind of function describes this type of sequence? Assist the student in applying methods for writing linear functions given two ordered pair solutions to writing function rules for arithmetic sequences.Writing a Function Rule Unit 4.

Example 1: Write a function Rule for each table x 3 2 4 5 6 4 6 8 10 12 y x 8 10 12 14 16 1 3 5 7 9 y.

This is the Harder of the two Function rules from tables When X=0, what does Y=?.

A table of values shows a list of the values for an independent variable, x, Develop a Rule When Given a Table of Values.

Writing an Equation for a Table of Values. Next use the function to look at the table of data and compare it to the given table. x: y Write a function rule. Feb 23 Functions Function Rules Function Value.

Top voted answer by Charles S. What is the rule for this function table X:0,1,2,3,4 Y:7,8,9,10,11 And after you find the rule tell me whats the Value of y when x = 8. Then i need to know what would be the value of. SOLUTION: Explain how to write a function rule from the table below.

Then write a function. X 2 4 6 _____ Y 1 0
