Only need the graph and 1-4 at bottom. 

Sketch the graph of
x < -1
- 1< x < 1
1 < x < 2
2 < x
Зх + 4,
2х + 3,
f (x) = {4x + 1,
Зх — 2,
-
X =
-1,1,2
Evaluate the limits that exist.
lim f(x); lim f(x), and lim f(x)
X→-1+
а.

x→-1
b.
lim f (x); lim f(x), and lim f(x)
x→1-
x→1+
c. lim f(x); lim f(x), and lim
С.
X→2-
f (x)
x→2+
Answer the each of the following.
1. At what points is f discontinuous from the left?
2. At what points is f discontinuous from the right?
