Given the <span>piecewise function f(x) is defined below </span>
In the piecewise function, we use the top function, when x has a value from -4 to 1, 1 not included. We use the middle function when x has a value from 1 to 2, 2 not included. And we use the bottom function when x has a value of 2 and above.
Therefore, to find f(1), we make use of the middle function.
