Test on Thursday, October 6h

Here are the topics for Thursday's test:


1.Linear equations:  using point-slope form to find equations of lines given:  slope and a point, two    
       points, line to be parallel to, line to be perpendicular to

2. Transformations of functions (powers, roots, absolute values, greatest integer) : translated, dilated,
      reflected over x-axis   NO GRAPHING CALCULATOR ALLOWED!

3. Domains and ranges of functions

4. Piece-defined functions

5. Polynomial functions:  zeros, max/mins, end-behavior, finding all zeros exactly using long division
     and quadratic formula

Unit 1 Test

EXPLANATION OF MY COLOR CODING:
GREEN:  problems I am least concerned about;  a small amount of review and most of you should do fine
RED:   problems that concern me;  you don't study up on these most of you are in trouble!!!
BLUE:  "intermediate" problems

1 problem: Plugging a number into a function involving [ ] (greatest integer function)
1 problem:   Finding the value(s) of x excluded from the domain of a root function
1 problem:  Finding the value(s) of x excluded from the domain of a function that is a fraction
2 problems:  Solving polynomial equations (and stating how many additional solutions not "visible") using technology
1 problem:  Solving a 1-variable second degree inequality using technology
3 problems:  Composition of functions -->  fog, gof, and f(f(f( )))
1 problem:  "Prove" that two functions are inverses using the definition of inverse fog = gof = x
2 problems:  Determine if functions are inverses (any method)
1 problem:  Graph a function's inverse, determine if the inverse is a function
1 problem:  Given a point, find the corresponding point symmetric to it with respect to the x-axis, y-axis, and origin.
1 problem:  Given a portion of a graph, complete it so that it has x-axis, y-axis, origin, and y = x symmetry
4 problems:  Determine if an equation exhibits x-axis, y-axis, or origin symmetry
3 problems:  Determine if a function is even, odd, or neither
1 problem:  Algebraic linear programming problem (constraints and function given)
1 problem:  "Set up" an everyday linear programming problem
