Problem
If $f(x)=-3|x-5|$, find $f(2)$ \[ f(2)= \]
Solution
Step 1 ：Let's find the value of the function $f(x)=-3|x-5|$ at $x=2$.
Step 2 ：Substitute $2$ for $x$ in the function to get $f(2)=-3|2-5|$.
Step 3 ：The absolute value of $2-5$ is $3$, so $f(2)=-3*3$.
Step 4 ：Simplify to get $f(2)=-9$.
Step 5 ：So, the final answer is \(\boxed{-9}\).
