Resumo de Recurso

Algebra and Function
  1. Transformations
    1. y = f(x) + a
      1. Translation ( 0 , a )
        1. Moves the graph up a units
      2. y = f(x - a)
        1. Translation ( a , 0 )
          1. Subtracting a from x shifts the graph to the right
        2. y = -f(x) is a reflection in the x-axis
          1. y = f(-x) is a reflection in the y-axis
          2. y = af(x) is a stretch in the y direction by a
            1. y = f(ax) is a stretch in the x direction be a^-1
            2. For y = f(|x|) for x > 0 and reflects in y to the right
              1. For y = |f(x)| for y < 0 reflected in the line of the dotted x-axis
            3. Functions
              1. A function is defined by:
                1. A rule connecting the range and domain sets
                  1. For each member of the domain, there is only one range value
                  2. A Function y = f(x)
                    1. One to One: One X value maps to one Y value
                      1. Many to One: More than one value of X maps to one value of Y
                      2. Composite Funtion
                        1. fg(x) = f(g(x)) Put g into f
                          1. The output of g becomes the input of f
                          2. Can only be formed in the example of fg(x). When the range of g is in the domain of f
                          3. Inverse Function
                            1. f^-1(x)
                              1. These can only exist when f(x) is a one to one mapping
                              2. The range of f is the domain of f^-1 and vice versa
                                1. The graph y=f(x) is the reflection of y=f^-1(x)
                                2. To turn f(x) into f^-1(x). Replace the x with y's and vice versa then make y the subject.
                              3. Modulus Function
                                1. |x| = x if x > 0
                                  1. |x| = -x if x < 0
                                  2. |x| < a = -a < x < a
                                    1. |x| > a = x < -a or x > a
                                    2. |x -a | = x - a for x >= a
                                      1. |x - a| = -(x - a) = a - x for x
                                      2. |x - b| <= a = -a < x - b < a
                                        1. |x - b| >= a = b - a < x < a - b
                                        2. |f(x)| = a <==> f(x) = a or f(x) = -a
                                          1. |f(x)| = |g(x)| <==> (f(x))^2 = (g(x))^2
                                          2. Mod graphs will never go below the x-axis
