Funktionen f(x) er stykkevis defineret:
f(x) = 3x-1  for x i [-3,1[
f(x) =  x^2-6x+7  for x i [1,6[
f(x) =  -x+13  for x i [6,10]
Tegn f(x).
Lavet:  f(3)=-2 og f(6)=7 
Løs ligningen f(x) = 4
To løsninger: x=5.45 eller x=9

f1(x) = If[-3 ≤ x ≤ 1, (3 * x) - 1]
f2(x) = If[1 ≤ x ≤ 6, x^(2) - (6 * x) + 7]
