Hey Guys Hope you are Fine , i need some Help with those numbers i got a lot of them
determine For f-1
1)f: x --> (radical) x ^ 2 x E R
2) f: x ---> x ^ 2 for x = and > 0
- X ^ 2 <0
3). f: x ---> sinx, x E R
4)f: x ---> x 2 / x-1, x # 1
5)f: x --> x ^ 2-4x 3 / x ^ 2-4x-5, s E] 5 + infinity[
6)Show that the function:
F: x --> x ^ 3-x, x E [1,3] admits a function reciproque
N.B: f-1 --->
Thanks in advance
