Use the following function rule to find f(8).

f(x)	 = 	
10	
x
 − 	7

f(8) = 


To find \( f(8) \) using the function rule \( f(x) = 10x - 7 \), we need to substitute \( x = 8 \) into the function.

\[
f(8) = 10 \cdot 8 - 7
\]

Now, perform the multiplication:

\[
f(8) = 80 - 7
\]

Subtract to get the final result:

\[
f(8) = 73
\]

So, \( f(8) = 73 \).
