Piecewise function is a function f(x) defined piecewise, that is f(x) is given by different expressions on various intervals.
The graph below shows the piecewise function f(x) = |x| if x ≤ 0
= sinx if x > 0
A. Graph A
B. Graph B
C. Graph C
D. None of these
Correct Answer: B
Step 1: The graph of the piecewise-defined function
f(x) = cosx if x <>
= ex if x ≥ 0 is as shown below. [Use a grapher.]
