Let  be defined by

$f(x) = \left\{ \begin{array}{cl} 2-x & \text{ if } x \leq 1, \\ 2x-x^2 & \text{ if } x>1. \end{array} \right.$\

Calculate .

Oops, the quesiton is "Calculate f(-3) + f(0) + f(3)".

-3 is <= 0 so the top equation applies       f(-3) = 2 - -3 = 5

o is <= 1    so the top equation applies     f(0) = 2-0 = 2

3 is > 1      so the bottom equation applies  f(3) = 2(3)-(3)^2  = -3

5 + 2 -3 = 4
