The Answer of Sketch labeled graphs of each function $f ( x ) = ( x - 1 ) ( x + 2 )$ by hand. As part of your work make sign charts for the signs, roots and undefined points of $f , f ^ { \prime } \text { and } f^{\prime \prime }$

Sketch Labeled Graphs of Each Function f(x)=(x−1)(x+2)f ( x ) = ( x - 1 ) ( x + 2 )f(x)=(x−1)(x+2)
