transormations: what i member abt the transformations is that when you have f(x)= x^2+1 it means thatt you have to shift the function 1 up.

Trig is mostly all abt using and understanding the unit circlee, if you do not know it then trig can become hard.

what i dont understand is how to do tranformations tha good on sec csc etc , also i dont understand how to graph the functions and their domain and range.

Logs and Inverses

one concept i learned was how to solve for the inverse. By solving an inverse all you do is switch the x and y so that the for the equation you solve for y.

another thing i learned was to solve certain logarithms because of the story ms. hwong told us. for example, log base 2 of x-5=2 you move the base 2 to other side making it x-5=2^2 which equals 4 then you solve for x and you get x=9

i also learned that when you use a horizontal line test and the function does not pass then the inverse wont pass the vertical line test therefore the function is not one-to-one.

i learned that the natural log is log base of 10 and when the log dont have a base it has the base of 10.

What i dont understand is how to graph logs?
Also i dont understand how to solve natural logs and e??

Even && Odd !! =]

Even: When a function is even the equation is f(-x))=f(x), which means that the function is symmetrical on the y-axis. When this function is graphed it is going to a reflection on the y-axis from quadrant 1 to quadrant 2.


Odd: the equation to find out if the function is odd is f(-x))=-f(x). This means that the function will be graphed symmetrical to the origin. When this function is graphed it is going to be reflected over the y-axis and then the x-axis leaving the function on quadrant 3 if the normal function is in quadrant 1.
