posted by confusedplease help .
given the following piecewise function
x+11 for 9<=x<3
y= { 2 for 3<=x<=2
2x6 for 2<x<=5
a. find the domain
b. find the range
c. find the intercepts
d. is f continuos on its domain. If not, state where f is discontinious
e. graph the function
This symbol { should be around all three lines.
PLEASE SHOW WORK

domain is all x where f is defined: [9,5]
range: (2,8]
intercepts: (3,0)
discontinuous at x=3,2
