Answer:
First, we can find the formula for the subtraction without substitution:
f
(
x
)
−
g
(
x
)
=
(
3
x
−
4
)
−
x
2
We can now substitute the values for the functions:
f
(
3
)
−
g
(
2
)
=
(
(
3
×
3
)
−
4
)
−
2
2
We can now solve the equation:
f
(
3
)
−
g
(
2
)
=
(
9
−
4
)
−
4
f
(
3
)
−
g
(
2
)
=
5
−
4
f
(
3
)
−
g
(
2
)
=
