Answer: a piecewise function is a function that is defined on a sequence of intervals.
Step-by-step explanation:
A piecewise function is a function that is "different" at different intervals.
The function may behave linearly between x = 0 and x = 10, and after that point, the function may be constant for a while, then change again.
This type of functions can be written as:
f(x) = g(x) if x1 ≤ x ≤ x2
f(x) = h(x) if x2 ≤ x ≤ x3
f(x) = k(x) if x3 ≤ x ≤ x4
and so on, where g(x), h(x) and k(x) are different functions, and those functions only act on the givenintervals: (x1, x2), (x2, x3) and (x3, x4)
