Please complete the follow problems neatly. Clearly label each problem, show all work, and use Microsoft Word’s equation editor to properly format all mathematics
1. Solve the following equations
a. 3x+3
h
b. e8-2x = e-3
c. log.(3x – 10) = log: 5
d. e3x = 25
e. 4 In 3x = 15
2. Describe the transformation of the graph of f(x) = 6* that yields the graph of(x) = 6*+1
3. For the following function f(x) = log(x – 3) + 1
a. Find the domain.
b. Find the x-intercept.
4. Use the properties of logarithms to expand: In xeyaz
5. Use the properties of logarithms to condense: 3 ln x – 2 ln(x + 1)
Each problem/part is worth 5 points for a total of 50 points. Points are awarded as correct or not correct – there is no partial credit for these problems.
