List domain and range. Determine the inverse "verbally," graphically, & algebraically, if one exists.

1. f(x) = sqrt(x - 6) + 2

domain: x > 6

range: y > 2

inverse: f ^-1(x) =

2. f(x) = 3x + 4

domain: all real numbers

range: all real numbers

inverse: f ^-1(x) =

3. y = 1/(x + 5) - 2

domain: x is not -5

range: y is not -2

inverse: f ^-1(x) =

4. Find inverse algebraically.
