For both questions below:

(a) Find the domain of the function.

(b) Locate any intercepts.

(1)

.....{3 + x......if -3 <or= to x < 0

f(x){3...........if......x = 0

.....{Sqrt{x}..if......x > 0

=======================

(2)

..........{1/x.........if.....x < 0

f(x) = {sqrt{x}...if.....x >or= to 0

NOTE: It is hard to correctly type the piecewise-defined functions using a regular keyboard.

I hope you can understand the above.
