Piecewise Functions: When a function is defined by different equations on different parts of its
domain, it is called a piecewise-defined function.
6. Consider the piecewise function: f(x):
=
√x+2
√x² - 1
1<x<6
x ≤1
a) What is the domain of this function?
b) What is f(0), f(1), f(−2), f(2), f(5). Is it possible to find f(7)?
c) Sketch a graph of the piecewise function.
