  1. Warm - Up Solve the following equations (for x)

  2. Solving Exponential & Logarithmic Functions Section 3.4

  3. Objectives Students will be able to… • Use log properties to solve exponential equations • Solve equations with variables in the exponents • Evaluate logs and natural logs • Use the change of base formula to evaluate logs with bases other than 10

  4. Strategies for solving Exponential andLogarithmic Functions • Rewrite the original equation in a form that allows the use of the One-to-One Properties of exponential or logarithmic functions • Rewrite an exponential equation in logarithmic form and apply the Inverse Property of logarithmic functions ( and ) • Rewrite a logarithmic equation in exponential form and apply the Inverse Property of exponential functions. ( and )
