Sink or Swim Embedded Assessment 1 Review for

Sink or Swim (Embedded Assessment 1 Review for chapter 2) Good Luck……

Directions: • There are four teams. • The first person from a team to raise their hand, will be selected by the teacher. If the person answers correctly he can choose to ‘swim’ or ‘sink’. • IF they choose to ‘swim’, they will add 2 pts to their score, or they can add 2 pts to another teams score (if they feel generous, or want an ally. . ) • IF you choose to ‘sink’, you can subtract 2 pts from another teams score. (muhahaha) • The team with the most points at the end of the game WINS!!!!!!

• What is the Domain of this function?

Choose the correct statement A circle is graphed on a coordinate plane: A circle is a function because each input has exactly one output. A circle is not a function because it does not pass the vertical line test.

Answer • NOT A FUNCTION

Define Independent and Dependent Variables. Give an example to justify.

Answer • Independent X, Dependent Y • DRY MIX Dependent Responding Y Measurable Independent X

Use your arms to… • Be able to represent a slope that is undefined, zero, positive and negative

You are hiking down hill at Red River Gorge. What is the slope of your experience (shown in the table) X (Time) Y(Elevation) 0 minutes 8300 ft 10 minutes 7900 ft 20 minutes 7500 ft 30 minutes 7000 ft

Answer • Your elevation is decreasing 400 ft per 10 minutes. The slope therefore is -40. You are decreasing in elevation 40 ft every minute.

What is the Range of this function

Answer • [-8, 8] • -8≤x≤ 8

Fill in the blank • An_____shows the relationship between two elements, written in a specific order using parentheses notation and a comma separating the two values. • _____is a visual representation of a relation in which an arrow associates each input with the corresponding output.

Answer • Ordered Pair • Mapping
