One-to-One Property...4

Section 3.1
46 & 48



Question 46

e^(2x - 1) = e^4

The base e is the same on both sides.

2x - 1 = 4

2x = 4 + 1

2x = 5

x = 5/2

Question 48

e^(x^2 + 6) = e^5x

x^2 + 6 = 5x

x^2 - 5x + 6 = 0

(x - 3)(x - 2) = 0

x - 3 = 0

x = 3

x - 2 = 0

x = 2

NOTE: We will continue with precalculus this week and back to calculus 1 next week.
