7.. 3.8 ws
8.. review packet (the first one)
4. even and odd... we seem to still be having problems with even and odd.
EVEN: symmetric to the y - axis (aka the vertical line x = 0)
with an even graph, when you plug in the opposite x value, you get the same y value.
(x, y) -> (-x, y)
even can shift up and down and still be even (symmetric to x = 0)
if even shifts right or left, it isn't even anymore, but it is symmetric to the vertical line x = #.
ODD: symmetric to the origin (aka the point (0, 0))
with an odd graph, when you plug in the opposite x value, you get the opposite y value.
(x, y) -> (-x, -y)
can not shift at all. if it shift R/L or U/D it is not odd anymore, but is still symmetric to the point where the origin shifted to.
5.. other stuff...
know all the graphs and how the shift (3.2)
understand what happens to statistical measures when a value is added or subtracted to a data set (3.3)
odd? even? neither? symmetric to what? (3.4)
know how graphs stretch/contract: if y = 2x^2, y values are x2 (x values don't change).
if y = (2x)^2 then x values are divided by 2, and y values don't change. know all that stuff -> x, opposite, y, same (when its not written on the y side) (3.5)
section 3.6 is the same as 3.3, but now the data set values are being multiplied/divided. know how each statistical measure is affected or not changed.
f(g(x)) and f(g(4)) - composite functions. start inside, and work your way out (3.7)
inverse functions. know how to find the inverse (switch x and y, and solve for y) and know how to check to see if a pair of functions are inverses of one another -> f(g(x)) = x and g(f(x)) = x
