Problems that will show up on 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

EXTRA CREDIT PROBLEM DUE 9/25:

"How much larger is each angle of a regular 20-sided figure than each angle of a regular octagon?"

Show all work, computations and remember that sharing an answer with a classmate actually reduces your extra credit points!

Football Players and Managers

Please be registered for MathXL before you come to school Tuesday.  Follow the directions on the sheet I gave you and then you will need this course ID:   XL04-01AS-501Y-2U63   (that is a zero in the first set of four, and a zero in the third set, but the letter O in the second set)

Be sure to pick a username and password that you can remember!  Write it down somewhere!

Assignment was slightly revised:
p10 #32-47(skip 38,39), 54-57 (use Desmos)

I never made my own, but these videos could help:
