However, for example, if the equation is:

Annenberg Teachers' Lab Patterns in Mathematics: Mystery Operation This challenging function machine takes user input for two variables to produce an output. After examining a series of input pairs and outputs, the user tries to deduce and apply the mystery operation to predict the output for a pair of machine-generated inputs.

An example of a mystery operation in this machine is: The standards overview for grades expects the understanding that "in the 'real-world,' functions are mathematical representations of many input-output situations. You might draw from the following examples: A soda, snack, or stamp machine The user puts in money, punches a specific button, and a specific item drops into the output slot.

The function rule is the product price. The input is the money combined with the selected button. The output is the product, sometimes delivered along with coins in change, if the user has entered more money than required by the function rule.

Circumference of a circle is a function of diameter. Students can measure the diameter and circumference of several round containers or lids and record that data in a table.

If diameter is the input and circumference is the output, what's the function rule? As they divide each container's circumference by its diameter to find that rule, they should notice a constant ratio -- a rough approximation of pi.

Arm length is a function of height. Miles per gallon A car's efficiency in terms of miles per gallon of gasoline is a function. If a car typically gets 20 mpg, and if you input 10 gallons of gasoline, it will be able to travel roughly miles. The car's efficiency may be a function of the car's design including weight, tires, and aerodynamicsspeed, temperature inside and outside of the car, and other factors.

Basic economics and money math: A weekly salary is a function of the hourly pay rate and the number of hours worked.

Rules of calculus - functions of one variable. Derivatives: definitions, notation, and rules. A derivative is a function which measures the slope. It depends upon x in some way, and is found by differentiating a function of the form y = f (x). Now, add another term to form the linear function y = 2x + The next rule states that when the. Write a linear function that describes the cost, C, for the shirts in terms of q, the quantity ordered. Then find the cost of order 20 t-shirts. Page 6 (Section ) 7. The cost, C, of water is a linear function of g, the number of gallons used. If gallons cost $ Find a linear function that represents a real-world relationship that is given verbally. Functions are written using function notation.

Compound interest is a function of initial investment, interest rate, and time. As price goes up, demand goes down. Shadows The length of a shadow is a function of its height and the time of day. Shadows can be used to find the height of large objects such as trees or buildings; the same function rule ratio by which we compare the length of an upright ruler to its shadow will help us find the unknown input the height of the large object when we measure its shadow.

Polyhedra As they examine the relationship between the number of faces, edges, and vertices of various polyhedra, can students discover Euler's rule?In mathematics, a linear combination is an expression constructed from a set of terms by multiplying each term by a constant and adding the results (e.g.

a linear combination of x and y would be any expression of the form ax + by, where a and b are constants). Example 6: Write a function rule to represent each situation.

A) the total cost C for pounds of copper if each pound costs $ B) the amount of your friend's allowance if the amount she recieves is.

A function is a relationship in math between two variables, often x and y, and for every value of x there is exactly one value of y. The x value is referred to as the independent variable and the .

The Standard Form for a linear equation in two variables, x and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.

If we have a linear equation in slope-intercept form. Improve your math knowledge with free questions in "Slope-intercept form: write an equation from a word problem" and thousands of other math skills. Students will write a function rule for an IPod commercial using cost to air and cost to make the commerical.
