Math gurus need your help!!!
f(x)=
x+1 if -infinity < x < -1
1 if x = -1
-x^2+1 if -1 < x < 1
x-1 if 1 <= x <= 2
-x+2 if 2 < x < +infinity
1. Where does f(x) have a limit?
2. Where is f(x) continuous?
3. Where is f(x) differentiable?
I'd also appreciate if someone could also tell me the domain and range of these 2 functions:
G(z)= 4/z^3
F(y)= 1 - 2*(y^1/2) (one minus 2 times radical y)
WILL REP.
