We can now summarize this into a piecewise function: 6x, for 1 ≤ x ≤ 5 50, for x ≥ 6 This piecewise function represents the cost of f (x) for x
A piecewise function is a function built from pieces of different functions over different intervals. For example, we can make a piecewise function f (x) where f (x) = -9 when -9 < x ≤ -5, f (x) = 6 when -5 < x ≤ -1, and f (x) = -7
