|
vertical line test
|
the way to determine whether a graph is a function. it is a function if the line passes through only one point.
|
|
|
function
|
for each x there is one y
|
|
|
domain/range
|
domain - allowable x values (input)
range - allowable y values (output) |
|
|
even function
|
f(x) = f(-x)
|
|
|
odd function
|
(think y=x3)
f(-x) = -f(x) |
|
|
Vertical and Horizontal shifts...
|
f(x)+/-c -> graph moves up/down c units
f(x +/- c) -> graph moved left/right c units |
|
|
absolute vlue transformation
|
after moving graphs appropriate units nad direction, have to move anything below x axis above axia
|
|
|
reflection
|
-f(x) -> flips graph around x-axis
f(-x) -> flips graph around y-axis |
|
|
Stretches and Compressions
|
cf(x) -> stretches vertically by factor of c
1/c(f(x)) -> compresses v. by c f(cx) -> compresses horizontally by c f(1/c x)) -> stretches H. by c |
