lxl<a
-a<x<x
a³+b³
(a+b)(a²-ab+b²)
lxl=a
lxl=a or lxl=-a
switch x and y
inverse
make f(x)= 0 and solve or graph and fins x-intercept
To find a zero
Order does not matter (menu 5, 3)
combination
a²-b²
(a+b)(a-b)
lxl>a
x>a or x<-a
Menu 6,5,3 µ= mean σ=standard deviation
Normal distribution
n√x^m
X m/n
a³-b³
(a-b)(a²+ab+b²)
x-intercept also means
Root, Zero
How many roots given equation
positive, two real Zero, one real Negative, two imaginary
grouping changes
associative
X's (Left to right)
Domain
As x→-infinity, f(x)→
Whats happening on the Left
Y's (bottom to top)
Range
"cut" one "bounce" two "twist" three
Multiplicity
Negative slope, only want x-values
Decreasing
As x→infinity, f(x)→
Whats happening on the right
X by reciprocal (will get one)
Inverse for X
Add 0 (will get same)
identity property of addition
Order matters menu 5, 2
Permutation
F(g(x))
write f BUT replace the x's, fill in the () with g
Positive slope only want x-values
increasing
multiply by 1 (will get same)
identity property of multiplication
Add opposite (will get zero)
Inverse property of addition
Order changes (around = sign, will have two = signs)
Symmetric
Order changes around operation
commutative
4(i-9)=4i-36
Distributive
Linking ideas (will have 3 = sign)
Transitive
Exactly same on both sides of = signs
Reflexive
