WHAT ARE THE FIRST FIVE KEY WORDS IN COMPETANCY FUCTIONS
QUADARATIC
EXPONTENTIAL-GROWTH AND DECAY
RATION-INVERSE
WHAT ARE THE FIRST FIVE KEY WORDS IN COMPETANCY FUCTIONS-TTHE LAST 3 WORDS
ABSOLUTE VALUE
ROOTS, SOLUTIONS, ZEROS
TRANSFORMATIONS
FIRST DESCRIPTOR HIGHLIGHTS
1 KNOW THE GENERAL SHAPE OF THE NON-LINERA FUCTIONS AND THE GRAPH CHARACTERISTICS
2ND DISCRIPTOR HIGHLIGHT
KNOW HOW TO USE THE GRAPHS AND THE CHARACTERISTICS WIHT THE EQUATIONS
3RD DISCRIPTOR
USE THE RELATIONSHIPS BETWEEN AND AMONG THE FUNCTIONS
THE FOLLOWING FUNCTIONS HAVE ONLY ONE TURN-2 EXAMPLES
PARENT=X^2, Y=X^2-2X-8
TO SOLVE A QUADRATIC BY FACTORING: THESE SOULUTIONS CALLED ROOTS, ZEROS, OR X-INTERCEPTS-DEFINE X^2-2X-8=0
(X+2) (X-4)=0
X+2=0 OR X-4=0
X=-2 OR X=4
USED FOR: AREA-HEIGHTS OF OBJECTS INVOLVING GRAVITY
EXPLAIN EXPONETIAL NON-LINEAR FUNCTIONS AS Y=2^x
used for growt as in population, bacteria
decay as in radioactive isotopes and carbon dating, and compound intrest
pop.growth, bacteria,
decay as in radioactive isotopes, carbon -dating, compound intrest
what non -liner functions are these Parent
y= [ x } absolute review on page 63 -2, positive 2, negative x-1, y =+1
rational functions and inverse variation functions have the variable in the denominator
y=1/x, y=2x-5/x-3-study graphs on pg 64 15
what functions have the variable in the denominator
rational funcctions-proportions are releated because they can have___________in the denominator
variable
v
When our Aymptotes: Touch-me-Nots: no matter how clese the function gets to the asymptote, the function never touches it.
Finding the vertical asymptote algebriacally: find the values of x that will work with the deonominator=0
Rationals, proportionas and Asymptotes, are used for what kind of work
WORK PROBLEMS,
ELECTRICITY PROBLEMS
HEAT LOSS

TRANSFORMATIONS ON FUNCTIONS NAME THE THREE TYPES
TRANSLATION
DILATION
REFLECTION
T D L
DEFINE THE TRANSFORMAION; TRANLATION FUNCTION;-EXAMPLE PAGE 64
MOVES THE FUNCTIN UPWARD OR DOWNWARD
TRANSLATION EXAMPLE PAGE 64
DEFINE THE TRASFORMATION DILATIONS
STRETCHES IT VERTICALLY, GETS SKINNEY AND NARROW
DILATION HORIZONTALLY-STRECHES IT WIDER
WHAT GETS SKINNIER AND NARROW
THIS IS WHAT HAPPEN WHEN DILATION GETS WIDER EXAAMPLE BOTTEM OF PAGE 64
WHAT HAPPENS WHEN YOU HAVE A REFLECTION DIALATION?
REFLECTS IN ON THE Y AXIS
EXAPMPLE TOP RIGHT PAGE 64
SAMPLE EXERCISE 1 BOTTEM OF PG 64-OBSERVE GRAPH SELECT TEH CORECT EQUAITON FORETHE PARABOLA
D) Y=2X^2 -4X -3. SOLUTIONS: THIS IS NOT ABOUT WRITING AN EQUATION. iT IS ABOUT RECOGNIZING IF X=0, THE INTERCEPT WILL BE CONSTANT
DEFINED ON SD ALG 2 DISC
WHY WOULD -2X^2 +12X-9 NOT BE THE ANSWER FOR THE PARABOLA?
A) HAS A NEGATIVE TWO IN FRONT OF IT CAUSING TO POINT DOWNWARD. IT DOESN;T WORK WITH ANWERS WITH POSIVE Y INTERCEPTS
15-EXERCISE 2 REVIEW AND UNDERSTAND CONCEPTS
DO YOU GET THE POINT-DO IT ON YOUR OWN
DEFINATIONS OF A QUADRATIC EQUATION
THEY ARE SECOND DEGREE EQUATIONS IN ONE VARIABLE IN THE FORM OF AX^2+BX+C=0, WHERE A, B, C ARE REAL NUMBERS AND A DOES NOT = 0
WHAT IS THE STANDARD QUAD EQUATION?
DEFINATIONS OF A QUADRATIC EQUATION-PROPERTY
IF A AND THere REAL NUMBERS AN (A) THEN EITHER A=0 OR B=0 OR BOTH EQUAL 0. AT LEAST ONE THE NUMBERS HAS TO =O
IN THIS STEP IS WHEN A=0 OR B=0
STEPS IN QUADRATIC EQUATIONS-
1) set the EQUAL TO ZERO, combine like terms, write in descending order
2) FACTOR: if factoring is not possible, then go to step 3) SOLVE each resulting equation and check the substiutionss)
3 solve each resulting equaion and check
first three steps of quaradic equaions
The third step using the quadratic formula
x=-b(+,-) radical sign (b^2-4ac)/2a
only used when factoring is not possible
second step on using quadratic formula
a,b, and come from the sec. degree equation has been set equal to 0, a is the coefficient (number in front of the secon-degree term, b, is the coefficeint(number in fornt of the first degree term ( if no first-degree term is presen then b is zero), and c is the constant term (no variables showing) note:ax^2+bx+c=0
Second quaud equ step
Next three steps on using quadratic equation-
subtstitute the numerical values for (a, b, and c) into the quadratic formula
D) simplify completly
e) Write the two, answers, onw with a + in front of the radical expression and one with a (-) in fornt of the radical expression in the formula. complete any additional simplification to get the ansers in the required form
last three steps in solving with quadratic formulas
