2 point question (1) Write the definition for a relation.

2 point answer (1) A set of ordered pairs. Bazinga

2 point question (2) Write the definition for a function.

2 point answer (2) a relation where each x is paired up with a y. Bazinga

2 point question (3) Write the definition for discrete data and give an example.

2 point answer (3) Data that is counted. It has certain and specific values. Bazinga

2 point question (4) Write the definition for continuous data and give an example.

2 point answer (4) Data that is measured. It has a range of values. Bazinga

2 point question (5) What is the difference between linear and nonlinear graphs?

2 point answer (5) Linear graphs are straight lines whereas nonlinear graphs have curves. Bazinga

3 point question (1) Is this graph a function? Explain.

3 point answer (1) Yes, it passes the vertical line test. Also, every x has 1 y. Bazinga

3 point question (2) Is this graph a function?

3 point answer (2) No, it does not pass the vertical line test. The line would cross twice. That means that x is paired with 2 y’s. Bazinga

3 point question (3) Is this a function? xy

3 point answer (3) Yes, each x is paired with a y. It doesn’t matter if the y’s repeat. Bazinga

3 point question (4) Draw a graph that is direct variation.

3 point answer (4) Any line going through the origin. Bazinga

3 point question (5) Give me an example of an equation that is direct variation. Explain why it is direct variation.

3 point answer (5) y = # x You are not adding or a subtracting a number, so the y directly varies with the x by multiplication or division. Bazinga
