Identify Formula:
Identify the formula for
(
f
∗
g
)
(
x
)
(f * g)(x)
(
f
∗
g
)
(
x
)
.
(
f
∗
g
)
(
x
)
(f * g)(x)
(
f
∗
g
)
(
x
)
is the product of
f
(
x
)
f(x)
f
(
x
)
and
g
(

)
g(x)
g
(
x

.
(
f
∗
g
)
(
x
)
=
f
(
x
)
∗
g
(

)
(f * g)(x) = f(x) * g(x)
(
f
∗
g
)
(
x
)
=
f
(

g
(

Given Functions:
We have:
\newline
f

=
−

f(x) = -2x^2
f

=
5
x
+
5
g(x) = 5x + 5
g
(
x
)
=
5
x
+
5
\newline
Now, we need to multiply these two functions to find
(
f
∗
g
)
(
x
)
(f * g)(x)
(
f
∗
g
)
(
x
)
.
\newline
(

)
∗
(

)
(f * g)(x) = (-2x^2) * (5x + 5)
(

(
x
)
=
(
