:
To find the value of
f
(
3
)
f(3)
f
(

)
, we need to substitute
x
x
x
with
3
3
3
in the function
f
(
x
)
=
−

x
+
7
f(x) = -2x + 7
f
(
x
)
=
−

x
+
7
.
\newline
Calculation:
f
(

Perform multiplication and addition:
Now, we perform the multiplication and addition.
\newline
Calculation:
f
(

Add the numbers to get the result:
Finally, we add the numbers to get the result.
\newline
Calculation:
f
(
