Evaluate the following logarithms: 1 (a) log3 27 = -3 (b) ln e3 = 3 (c) log3 27 = 6 2. State the domain of - ln(x - 3) + 4 and sketch its graph. Here we have three transformations: shift right by 3, reection about the x axis, and shift up by 4. 3. Solve: (a) log6 (x - 3) = log6 16 x - 3 = 16 x = 19. (b) 2 ln x = ln 2x ln x2 = ln 2x x2 = 2x x(x - 2) = 0 x = 0, 2, but we must throw out 0 since it is not in the domain. 1 ...
