solve the equation

1. In x + In (x+12) =2

x= ? or either there is no solution

2. solve the exponential equation

9^x=6

What is the exact answer?

3. Use transformations to indentify the graph of the function. Then determine its domain, range, and horizontal asymptote.

f(x)=2^-x+1

x=? or either there is no solution
