How would you find the domain for f(x) = 2x - 4x^1/2 + 2 ?
How would you find the domain for f(x) = 2x - 4x^1/2 + 2 ? I'm not exactly sure what to do/what steps to take. Do you factor out a 2x1/2 from the whole problem and then get 2x1/2 times x2-3x+2?

Prove that 1 + sin b - cos b =2sin1/2b cos1/2b +sin1/2b
Prove that 1 +sin b -cos b=2sin 1 b cos 1 b +sin 1 b 2 2 2 and hence solve 1 +sin b -cos b =0 0 = <b=<2¶
