Answer :

To evaluate the function [tex]\( f(n) = n^2 + 5 \)[/tex] for [tex]\( n = 8 \)[/tex], follow these steps:

1. Substitute the value of [tex]\( n \)[/tex] with 8 in the function:
[tex]\[
f(8) = 8^2 + 5
\][/tex]

2. Calculate [tex]\( 8^2 \)[/tex]:
[tex]\[
8^2 = 64
\][/tex]

3. Add 5 to the result from step 2:
[tex]\[
64 + 5 = 69
\][/tex]

Therefore, the value of the function [tex]\( f(8) \)[/tex] is 69.
