Explain what a relation is and give an example.

y x Tell whether or not this graph is a function. Be able to explain how you know and give a counter example.

Draw an example of a discrete function and a continuous function. Be able to explain the difference between them both.

Explain the difference between inequality notation and interval notation in detail. Also give an example of each. Your explanation must include the words brackets, parenthesis, included, not included, open dot, closed dot, infinity..

domain range Draw two pictures of graphs that have an infinite domain and an infinite range. Be able to explain what domain and range are.

Draw an example of the direct variation graph and give the two formulas you can use to solve a direct variation problem.

direct variation inverse variation Give a real life example of something that has direct variation and something that has inverse variation. Be able to explain WHY? (think about the definitions we discussed in class)

Find y Find y when x = 1.5, if y directly as x and y = -16 when x = 6

The amount of paint mixture varies directly with its two component parts. If it takes 30 ounces of Part A mixed with 45 ounces of Part B, how much Part A will you need to mix with 90 ounces of Part B?
