QUESTION
Identify the maximum value of
f
(
x
)
=
−
4
(
x
+
1
)
2
+
9
f(x)=-4(x+1)^2+9
f
(
x
)
=
−
4
(
x
+
1
)
2
+
9
.
QUESTION
If
f
(
x
)
=
x
2
f(x)=x^2
f
(
x
)
=
x
2
and
g
(
x
)
=
(
x
−
4
)
2
g(x)=(x-4)^2
g
(
x
)
=
(
x
−
4
)
2
, how do their minimum values compare?
QUESTION
Identify which has greater output at
x
=
−
1
x=-1
x
=
−
1
:
f
(
x
)
=
x
2
+
2
f(x)=x^2+2
f
(
x
)
=
x
2
+
2
or
g
(
x
)
=
3
x
+
1
g(x)=3x+1
g
(
x
)
=
3
x
+
1
.

ANSWER
f
(
−
1
)
=
3
f(-1)=3
f
(
−
1
)
=
3
is greater than
g
(
−
1
)
=
−
2
g(-1)=-2
g
(
−
1
)
=
−
2
. Substitute
x
=
−
1
x=-1
x
=
−
1
into each function and compare results.
