We need to determine the value of the function when x is equal to -1, for the function below:


f(x)=\begin{cases}4x\text{ for }x\le-1 \\ x-2\text{ for }x>-1\end{cases}

The value of x is equal to -1, therefore we need to use the first expression:


\begin{gathered} f(x)=4x \\ f(-1)=4\cdot(-1) \\ f(-1)=-4 \end{gathered}

The function is equal to -4 when x is equal to -1.
