Answer

So, the value of \(f\left(-\frac{1}{2}\right)\) is \(\boxed{-2.5}\).

Steps

Step 1 ：Given the function \(f(x)=x-2\), we need to find the value of \(f\left(-\frac{1}{2}\right)\).

Step 2 ：Substitute \(x=-\frac{1}{2}\) into the function to get \(f\left(-\frac{1}{2}\right) = -\frac{1}{2} - 2\).

Step 3 ：Simplify \(-\frac{1}{2} - 2\) to get \(-2.5\).

Step 4 ：So, the value of \(f\left(-\frac{1}{2}\right)\) is \(\boxed{-2.5}\).
