  1. 11-4 Logarithmic Functions

  2. 2? = 1.23 We use logarithms to find missing exponents.

  3. How to write a logarithm… For example, 32 = 9 will be written as Log39=2

  4. We can evaluate a logarithm by setting it equal to x: Ex) Evaluate log8 64 Log864=x 8x=64 X=2

  5. You can graph logarithms by writing them in exponential form then plugging in values. Graph y=log3(x+1)
