How would I do this?
Determine its domain and range
f(x)= {2x+1 , x <0
f(x)= {2x+2, x >=0 (x is greater or equal to 0)
(a) f (f=1)
(b) f(0)
Here is the picture of the question.

(a) and (b) are just 2 extra parts of the question.
f(x)= {2x+1 , x <0
f(x)= {2x+2, x >=0 (x is greater or equal to 0)
I believe I would just do this, replace x with the number 1 for part (a), and then find the range and domain. Which I do not know how to?
f(x)= {2(1)+1 , x<0
f(x)= {2(1)+2, x >=0
