study guide Part 1:  Answers will follow.

Part 2 is ws. page 113-114

Answers:

Part 1: 1) Function because every input(x) has only one output(y) Nonlinear because the rate of change is not constant(not the same).

2) NOT A Function because the input 0 has two different outputs 5 and 6.

3)  Function because every input(x) has only one output. Linear because the rate of change is constant. Rate of change(slope is 5)

4) Not a Function because the input 0 has two different outputs, 3 and 5.

PART 2: Unit 2 PRACTICE p113-114

Answers:  1A) : Function, each input is paired with exactly one output.

1B): Not a function because the input 4 has two different outputs  2, -2

2) C, D      3) A, C, F        4) slope 3,   y-intercept 2  

5) The slope is -80, it represents  the number of miles 80 that is decreased from the destination per hour traveled.

6) A: shows Jordon rode his bike at a constant rate to the park.  B: Jordon stayed at the park  C:  Jordon rode at a constant rate toward home until  D: Jordon  got off his bike and walked he rest of the way home.
