Functions

Functions

1. Functions is a mapping which is either one-one or many-one mappings

   • Only has x

2. Domain: set of input values

   • X axis

3. Range: set of output values

   • Y axis

4. Inverse functions:

   • Do the opposite of the function
   • Graph is reflection in line y=x
   • Range of inverse function is same as domain of the original function
   • Special inverse functions:
     • f(x)=e^x
       • Graph=
     • f(x)= ln(x)
       • Graph=

5. Composite functions:
