20 – Understanding the Piecewise Function No Calculator

2. Piecewise Function – A function defined in piecesB C D
On [-10, 10], f(x) is undefined at: A
x = 0
x = 4

3. Identify, by letter, the piece in which each function value resides.
On [-10, 10], for what values of x is f(x) undefined?
x = -6
x = 5

4. Given the graph of f(x) below, evaluate the function at each value.–2 –1 6 –4
On [-10, 10], for what values of x is f(x) undefined?
