Evaluate a function
Full solution
Q.
Use the following function rule to find
f
(
41
)
f(41)
f
(
41
)
.
\newline
f
(
x
)
=
7
x
+
8
f(x) = 7\sqrt{x + 8}
f
(
x
)
=
7
x
+
8
\newline
f
(
41
)
=
f(41) =
f
(
41
)
=
_____
Substitute
x
x
x
with
41
41
41
:
To find the value of
f
(
41
)
f(41)
f
(
41
)
, we need to substitute
x
x
x
with
41
41
41
in the function
f
(
x
)
=
7
x
+
8
f(x) = 7\sqrt{x + 8}
f
(
x
)
=
7
x
+
8
.
\newline
So, we calculate
f
(
41
)
=
7
41
+
8
f(41) = 7\sqrt{41 + 8}
f
(
41
)
=
7
41
+
8
.
Add
8
8
8
to
41
41
41
:
First, we add
8
8
8
to
41
41
41
inside the
square root
.
\newline
41
+
8
=
49
41 + 8 = 49
41
+
8
=
49
.
Find square root of
49
49
49
:
Now, we find the square root of
49
49
49
, which is
49
=
7
\sqrt{49} = 7
49
=
7
.
Multiply by
7
7
7
:
Next, we multiply the square root we found by
7
7
7
. So,
f
(
41
)
=
7
×
7
f(41) = 7 \times 7
f
(
41
)
=
7
×
7
.
Perform final multiplication:
Finally, we perform the multiplication to get the result.
7
×
7
=
49
7 \times 7 = 49
7
×
7
=
49
.
