Please provide me a neat, readable, and complete solution. Thank you!

1.
Let
(r + 2)²,
if
I < -1
f(x) =
[1 - x],
if -1 <r <0
|2x – 3| – 1, if
I > 0.
(a) Give the r coordinate(s) of the possible point(s) of discontinuity of f.
(b) Determine if f is continuous at each a in (a). If not, identify the type of discontinuity
as removable, jump essential, or infinite essential.
(c) Redefine f(x) at all point(s) of removable discontinuity.
