19
Q

reflection across the x-axis

20
Q

reflection across the y-axis

21
Q

symmetrical to x axis

A

can fold across x axis

22
Q

symmetrical to y axis

A

can fold across y axis

23
Q

symmetrical to origin

A

can rotate upside down and its the same

24
Q

tell if its symmetrical to x axis algebraically to equation

A

y is replaced with -y and is the same

25
tell if its symmetrical to y axis algebraically to equation
x is replaced with -x and is the same
26
tell if its symmetrical to origin algebraically to equation
x replaced with -x and y replaced with -y and is the same
27
determine if an equation is even, odd, or neither
- all odd exponents=odd - all even exponents=even - both= neither
28
graph translation on test
show +- on coordinates | show new ordered pairs
29
find the intersection of the following interval pairs
U together | "and" what needs to overlap
30
find the domain and range of equation
- think of what the graph looks like | - what can x not be
31
difference quotient equation
f(x+h)-f(x) over h | - use f(x) equation and just (x+h)
32
find g of f and its DOMAIN
simplify completely then find what x can't be to make numerator or denominator zero
33
if the graphs intersect at exactly one point
- ordered pair | - consistent and dependent
34
if the graph are parallel
- equation doesn't equal - no solution - inconsistent and independent
35
if the graphs are on the same line
- equation equals each other - infinite number of solutions - inconsistent and dependent
36
x arbitrary
only for same line/infinite solutions | x, solve for y
37
solve systems with three equations
1. First 2 equation s | 2. Second 2 equations using same variable
38
matrix
10 01 - 0=add - 1= multiply
