Evaluating a piecewise function adds an extra step to the whole proceedings. We have to decide which piece of the function to plug-and-chug into. Since -3 is less than 2, we use the first function to evaluate x = -3. f(x) = x + 1. f(-3) = -3 + 1 = -2. The number 2 is our boundary between life, death, and the two pieces of our function.
