Outcomes
        In this lesson you will learn 
        - to combine two functions by multiplication 
 
        
By the end of this section students will be able to:
        - model problem situations with combinations and compositions of functions 
 
          - analyze relations, functions and their graphs 
 
          - use tables and graphs as tools to interpret combinations and compositions of functions 
 
          - represent complex numbers in a variety of ways

          - how to find the x and y-intercepts of functions 
 
          - how to find the vertex of a quadratic function 
 
          - the relationship between the vertex of a quadratic function and its maximum or minimum value 
 
          - symmetry as it relates to graphs of quadratic functions
