Problem
If $f(x)=-5 x+2$, find $f(-2)$ \[ f(-2)= \]
Solution
Step 1 ：The function \(f(x)=-5x+2\) is a linear function. To find \(f(-2)\), we substitute \(x\) with \(-2\) in the function.
Step 2 ：After substituting \(x\) with \(-2\) in the function \(f(x)=-5x+2\), we get \(f(-2)=12\).
Step 3 ：Final Answer: \(\boxed{12}\)
