# Write an equation for a function that gives the values in the table

Have the student explain the difference between an expression and an equation and how an equation can show the relationship between the dependent and independent variables.

Ask the student to distinguish dependent from independent variables given in equations, written descriptions, and real-world situations. What happens to g when n increases by one? Do you notice a pattern? Which variable is dependent? How do you know? What is a dependent variable?

What is an independent variable? The teacher asks the student to complete the problems on the Table to Equation worksheet. Clarify that both the dependent and independent variables change, though in different ways.

What happens to the test grade when the number correct on the test changes? Records the operation instead of the complete equation. Think of the function in terms of purchases. Clarify the difference between expressions and equations.

Then assist the student in mathematically representing this relationship with an equation. Sciencing Video Vault Represent the function as an equation that may be used for any added value to determine the cost of a purchase.

From the equation, you can determine the missing variable. Guide the student to write equations to model the relationship between the variables shown by the tables. Is it possible for s to equal 2 or 1? The teacher asks follow-up questions, as needed.

What happens to the number of diagonals when the number of sides changes? Questions Eliciting Thinking Which variable is independent dependent? Instructional Implications Ask the student to identify the independent and dependent variables and to verbally describe the relationship between them.

She has been published as a poet in "Fine Lines Magazine.Here is a list of all of the skills that cover functions and equations!

These skills are organized by grade, and you can move your mouse over any skill name to preview the skill. Q.6 Find values using function graphs; Q.7 Evaluate a function; Q.8 Evaluate a function: write an equation from a table; S Slope-intercept form: write an. Watch video · Consider the following table of values for a linear function f of x is equal to mx plus b and an exponential function g of x is equal to a times r to the x.

Write the equation for each function. And so they give us, for each x-value, what f of x is and what g of x is.

Often, students are asked to Write the equation of a line from a table of values. To solve this kind of problem, simply chose any 2 points on the table and follow the normal steps for writing the equation of a line from 2 points. Function Tables Team Desmos If you put an function of x in the 2nd header we'll fill it in as a function table, calculating the values for you.

basically, you take the header of the output column you want (lets say M) and write a generic looking equation using just letters. use.

Calculates the table of the specified function with two variables specified as variable data table. Encourage the student to analyze the relationship using a table or graph and then write an equation that reflects the relationship between the variables.

Almost There: but the value of the dependent variable is calculated for particular values of the independent variable.

It might be helpful to describe these variables in terms of an input.
