Identify Formula:
Identify the formula for
(
f
+
g
)
(
x
)
(f + g)(x)
(
f
+
g
)
(
x
)
. The correct formula is
(
f
+
g
)
(
x
)
=
f
(
x
)
+
g
(
x
)
(f + g)(x) = f(x) + g(x)
(
f
+
g
)
(
x
)
=
f
(
x
)
+
g
(
x
)
.
Substitute Values:
We have
f
(
x
)
=
2
x
2
f(x) = 2x^2
f
(
x
)
=
2
x
2
and
g
(
x
)
=
−
x
+
6
g(x) = -x + 6
g
(
x
)
=
−
x
+
6
. Substitute these values into the formula to get
(
f
+
g
)
(
x
)
=
