what is the domain of each of the following functions,their intercepts and thier range?
f(x)=x+3 and f(x)=-2x-3 if x<-2 and x>=-2
f(x)=x+3 and f(x)=-2x-3 if x<-2 and x>=-2

All polynomials have a domain of all reals numbers.
Just plug in x=0 to get the y-intercept, and f(x)=0 to get the x-intercept.
Since these are just lines, the range is also all real numbers.
Not sure what help the "if x<-2 and x>=-2" provides, since that pretty much includes all real numbers.
