Complete each table. then write a function rule for each relationship

The problem asks for 3 solutions. For examples such as in the first part, a question might come up along the lines of "Could we define a function using other letters in the word. A horizontal line has a slope of zero. For example, students might make the sequence of numbers to answer the question of how many fish are there in a lake after 10 months if at each month the number of fish doubles, but 10 die.

Lines with the Same Slope Lines with the same slope are either the same line, or parallel lines. You will need to discuss the minimum and maximum values to be shown for the x and y-axes, so their calculator graphs will look like the graphs on their worksheets.

When you're plotting data, slope tells you the rate at which the dependent variable is changing with respect to the change in the independent variable. The numbers m and b give the slope of the line m and the value of y when x is 0 b.

Questions Eliciting Thinking Can you write an equation that uses both variables. When you are dealing with data points plotted on a coordinate plane, a positive slope indicates a positive correlation and the steeper the slope, the stronger the positive correlation.

She can count just the number of cars and then multiply it by 4 because the number of tires is related in a predictable way to the number of cars. Is it possible for n to equal 30. If you drive a light, efficient car, you get better gas mileage.

Is it possible for s to equal 2 or 1. Can you determine how much the grade changes for each right question. Use the following TI activity to work with the students to write an equation for the relationship for x and y using a table to identify the pattern, and then graph that relation.

If we designate Point B as the first point and Point A as the second point, the value of the slope is the same: Below is one possible way to complete the table consistent with this rule. Type another value in the X column and push in the corresponding position in the Y column.

You want to choose x coordinates that are either multiples of the denominator or 0. Writes an expression instead of the complete equation. If there are no cars in the parking lot, then the number of tires is 4 times 0, or 0. For example, in Scrabble every word has at least two letters, so a second-letter function would be well-defined there.

How are the independent and dependent variables related in the table. It may lack some detail. You put one number into the machine and the recursion rule changes it and shows you the second number in the pattern. Explain that typically the value of the independent variable is freely chosen, but the value of the dependent variable is calculated for particular values of the independent variable.

Negative Slope When a line slopes down from left to right, it has a negative slope. The general approach is to use one method to develop a number pattern or sequence of numbers and then explore the pattern using other methods.

This equation is not in slope-intercept form. constant then the function is quadratic [graph is a parabola] and Write a rule to show the relationship between the number of pegs I. Build a table of 5 sample points that fit each rule.

Graph each rule. x y x y y = x - 3 2 y = 3x - 1 0 1 2 y = x + 0 1. Different function tables have different rules. Sometimes the rule is given, and you are asked to fill in the missing information on the function table using the rule. Sometimes the rule is not given, and you are asked to use what you observe about the relationship between the numbers to determine the rule.

Horizontal: Each value in the "green" column is multiplied by a constant to get the corresponding value in the "red" column.

Vertical: If the "green" value is multiplied by a number, then the "red" number is multiplied by the same number.

A function is a relation in which each input has only one output. In the relation, y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Each number in the sequence is called a term (or sometimes "element" or "member"), read Sequences and Series for a more in-depth discussion. Finding Missing Numbers To find a missing number, first find a Rule behind the Sequence. Algebra Examples.

Step-by-Step Examples. Algebra. Tables. Find the Function Rule. Calculate the value of using each value in the relation and compare this value to the given value in the relation. If the table has a linear function rule, for the corresponding value. This check passes since and.
