Warm-Up: February 13, 2013

Find the multiplier for 8% decay.

Is f(x) = 300(0.5)-2x exponential growth or decay?

Solve for x: logx4 = (1/3)

Write as a single logarithm:

log 3 + log 2x – log 6

Essential Question

How can we use logarithms to solve equations?


Example 1 page 407 24
Example 1: Page 407 #24

3 ln x + 3 = 1

e-4x – 22 = 56


Example 2 page 407 22
Example 2: Page 407 #22

ln x + ln(x + 1) = ln 2


You try 2 page 407 18
