(a) lim f(x), (b) lim f(x), and (c) lim f(x)
X1+
X+1-
X+1
X0-
for x < 1
(2x - 3,
4) f(x) = {1,
|-4x + 8,
for x = 1
for x > 1
Answer Yes or No and use all three parts of the definition
of continuity at a point to say why or why not.
x + 1
x2 - 8x + 15
5) Is the function given by f(x):
continuous at x = 3? Why or why not?
Find the limit, if it exists.
