Consider the function f(x)=2-3x with domain R ( real numbers). Let A = [-1,3), B=(2,5].

a.)Sketch the graph of XA•XB

(which has X with an A subscript and X with B subscript, i suppose means XA composite XB)

b.)Sketch the graph f|A•IB

Now i know how to graph XA and XB but im not sure what to do with a.) and i dont know what b.) is even asking.

Any help or suggestions. Much appreciated.
