#### Description:

In this activity, students plug values into a function to see what the output is for that function. Then based on that information, they have to guess the coefficient and constant for a linear function. This activity allows students to explore linear functions and what input values are useful to figuring out the linear function performed by the function machine. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

#### CCSS.Math.Content.6.EE.A.2c: Common Core State Standards for Mathematics

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

#### CCSS.Math.Content.6.EE.C.9: Common Core State Standards for Mathematics

Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.

#### CCSS.Math.Content.7.EE.A.1: Common Core State Standards for Mathematics

Apply properties of operations as strategies to add, subtract, factor, and expand linear expressions with rational coefficients.

#### CCSS.Math.Content.8.EE.B.5: Common Core State Standards for Mathematics

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.

#### CCSS.Math.Content.8.EE.C.7a: Common Core State Standards for Mathematics

Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).

#### CCSS.Math.Content.8.F.A.2: Common Core State Standards for Mathematics

Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

#### CCSS.Math.Content.8.F.B.4: Common Core State Standards for Mathematics

Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.

#### CCSS.Math.Content.HSF-IF.A.1: Common Core State Standards for Mathematics

Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).

#### CCSS.Math.Content.HSF-LE.A.1b: Common Core State Standards for Mathematics

Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
