Study guide for unit test algebra I

The unit test on functions (pt. II) is this Friday.  there will be 10 questions.

things to know

the parent functions
how to find domain and range
how to write an equation for a function or sequence
how to graph and solve an inequality
how to solve a SOE.

Knowing how to transform parent functions will make things a lot easier.


Here are some sample problems.

1.  graph:   y < -2x +3
2.  solve the SOE -     y = 5x - 14        y = 2x  - 5
3.  name the parent functions.
4.  what are the domain and range for each parent function?
5.  what is the 30th term in the sequence ( 50, 30, 10 ...)
6.  what is the equation for the sequence  (2, 7), (3, 11), (4, 15) ?
7.  What is the equation for the function (-1, -1), (0, 0), (1, 1) and (2, 8)

1.      8.   Write the function for the data (-1, 2), (0, 1), (2, 3), (3, 4) and (4, 5).
