Consider the functions
f
(
x
)
=
x
+
1
f(x)=\sqrt{x+1}
f
(
x
)
=
x
+
1
and
g
(
x
)
=
x
g(x)=x
g
(
x
)
=
x
on the interval
[
0
,
1
]
[0,1]
[
0
,
1
]
. Determine whether the graphs of
f
f
f
and
g
g
g
are guaranteed to intersect on this interval, and justify your conclusion using values of
f
(
x
)
−
g
(
x
)
f(x)-g(x)
f
(
x
)
−
g
(
x
)
at the endpoints.
