the endpoints of segment LE are L(-2,2) and F(3,1). the endpoints of segment JR are J(1,-1) and R(2,-3). what is the approximate difference in the lengths of the two segments?

Which statement best describes fx)=- 2x-7+1? -6 is in the domain of f(x) but not in the range of f(x). -6 is not in the domain of f(x) but is in the range of f(x). -6 is in the domain of f(x) and in the range of f(x). -6 is neither in the domain of f(x) nor in the range of f(x).
