well anyways, I'm working on applying domain and range to trig functions. I had a sheet of about 10 questions and 2 bonus ones. I got one bonus, but not the other and need help with another one on the work sheet.

Find the domain and range of:

f(x) = 2sin^-1(3x+4)-1

g(x) = sqrt[tan^-1(x^2 - 2) - pi/4]

Thanks for your help!
