Please help me solve these exercisesWhat is the Domain of the following logarithmic functions? 1) f(x) = log(3x – 21) 2) f(x) = log(2x + 16) 3) f(x) = log2 (x – 2) Perform the operations: 4) log2 4 + log4 2 = 5) log 1000 + ln e5 = Solve the equat

What is the Domain of the following logarithmic functions?

1) f(x) = log(3x – 21)

2) f(x) = log(2x + 16)

3) f(x) = log2 (x – 2)

Perform the operations:

4) log2 4 + log4 2 =

5) log 1000 + ln e5 =

Solve the equation:

6) x2 = log 100 + 90

7)Make a paragraph about an application of the Logarithmic Function to the real life and its importance.

On all the exercises show your work step-by-step.
