Notice that the graph looks like it is made of three pieces Because of this the function is called a piecewise defined function Piecewise defined functions are functions that have different descriptions for different values of the independent variable Here the piecewise defined function d where d t is the distance from home and t is time is defined over three time intervals if 0 t 20 d t 0 05t if 20 t 50 d t 1 Hint if 50 t 60 d t 0 1t 6 What is the expression for the distance d t for each time interval d t if 0 t 20 if 20 t 50 if 50 t 60
