  1. Algebra 2 Ch.8 Notes Page 59 P59 8-5 Exponential & Logarithmic Equations Part 1

  2. Exponential Equations An equation of the form bcx = a, where the exponent includes a variable, is an Exponential Equation. If m and n are positive and m = n, then log m = log n m n 3x = 4 73x = 20

  3. 62x = 1500 Graphing

  4. Solving Exponential Equations by Graphing 62x = 1500 Find the Intersection Point. X = ? You might have to adjust the viewing window to see where they intersect.

  5. 2(1.5)x = 6 Table

  6. Solving Exponential Equations by Tables Solve to the Nearest 100th 2(1.5)x = 6 Get everything on one side. Enter 2(1.5)x - 6 Look for Sign Change

  7. Zoology Example The US population of Bighorn Sheep was 1170 in 1971. The population was 335 by 1999. What year might only five Bighorn Sheep remain in the US if the decay rate remains constant? 1971 = year 0 Put the data into a list (0, 1170) and (28, 335) Use Exponential Regression to get the equation. Y = 1170 x .9563x
