Question

ill in the following:

lim f(x)= x→ 1 +
lim f(x)= x→ 1 −
lim f(x)= x→ 1
f (1) =
lim
x→−
lim f(x)= x→ 2 +
lim f(x)= x→ 2 −
lim f(x)= x→ 2
f (2) = f (x)=
lim f(x)= x→ 3 +
lim f(x)= x→ 3 −
lim f(x)= x→ 3
f (3) = lim f (x)=
x→
lim f(x)= x→ 4 +
lim f(x)= x→ 4 −
lim f(x)= x→ 4
f (4) =
y = f (x)
Name the x coordinate of any points where the function is discontinuous: ________

Answer 1
