Use a graphing calculator to graph functions:
a. use your graphing calculator to graph f(x)=|x+1| and determine where the function is increasing & decreasing.
a. increasing x < 1; decreasing x > 1
b. increasing x < -1, decreasing x > -1
c. increasing x > 1; decreasing x < 1
d. increasing x > -1; decreasing x < -1

b. select true or false: the function 4(x+4)(x-5)^3 > 0, when x < -4 or x > 5. true or false.
