Functions and Patterns Battleship Review

The Rules of War Place your team’s battleships on the coordinate plane. After a given amount of time, I will call on someone from the team to answer. (Make sure everyone on your team agrees on an answer!) If you answer a question correctly, you get to fire on the opposing team by stating ordered pairs. If you answer incorrectly, you do not get to fire. Try to sink the opposing team’s battleships. May the most knowledgeable team win!

Answer y = -3x

Write a function for this table. Both teams Write a function for this table. x y 0 -3 1 -1 1 3 3

Answer y = 2x-3

Is this a function? {(2, 4), (2, 5), (3, 7), (4, 9)}

No, it is not a function. The value 2 is paired with two different y values.

Is this a function?

No, it fails the vertical line test.

Explain the Correlation. The the age of a car and the number of miles that car has traveled.

Positive because as the age of the car increases, the number of miles the car has traveled increases.

Explain the Correlation. The time spent walking and a student’s English grade.

No correlation because time spent walking does not effect a person’s English grade.

Explain the Correlation. The age of a car and the sales price of the car.

Negative because as the age of the car increases, the car’s sale price decreases.
